The mid-season market is always a hectic time for top-flight clubs as teams look to bolster their ranks for the second half of the campaign.
It's more difficult to do business in the January window but several sides across the country may be forced to open their chequebooks after Christmas.
What are the latest rumours and headlines? talkSPORT.com takes a look…
Anthony Martial
Ralf Rangnick has told Anthony Martial to discuss his future with him personally after the striker's agent revealed that his client wants to leave Manchester United in January.
Martial's agent, Philippe Lamboley, said recently that he is seeking a move next month after falling out of favour this season.
Interim boss Rangnick said: "I don't communicate with agents via the media and press. The player hasn't spoken with me or us about it.
"After the final training session before the Crystal Palace game, after having trained with team, he informed the doctor and the medical department that he would not be available because the pain in his knee is too big. We have to wait and see.
"Maybe he can train again [on Sunday] but I have to speak to the doctor first. To be honest, what his agent says via the media is not of that much interest to me."
Dele Alli
Tottenham have given the green light for Dele Alli to go out on loan this January, according to reports.
The 25-year-old has started just five times for Spurs in the league this season, and his lack of first team football has led to club chairman Daniel Levy changing his mind regarding Alli's short-term future.
Rumours suggested the Tottenham owner denied Alli a loan move to Paris Saint-Germain last January.
However, according to The Athletic, now both Levy and Spurs' managing director of football, Fabio Paratici, see a temporary move away as the answer to reigniting his previous form.
Alli signed a new contract with Tottenham back in 2018 that secured him to the north London side until 2024.
Given that the midfielder currently cannot break into Spurs' starting XI and a big money move looking unlikely, a loan is hoped to provide the solution for the outcast ace.
Christian Pulisic
Barcelona are planning moves for THREE Chelsea players, according to Spanish outlet Mundo Deportivo.
The report states that and Christian Pulisic, 23, and defensive pair Antonio Rudiger, 28, and Cesar Azpilicueta, 32, are on the Catalans wish list.
The latter duo are entering the final months of their deals at Stamford Bridge and could agree pre-contract agreements with Barcelona ahead of a summer move.
Pulisic meanwhile has been targeted for a January loan swoop after a mixture of form and fitness has limited him to just six league appearances this term.
Divock Origi
AC Milan have reportedly added the Liverpool striker to a list of potential targets as the long-term replacement for Zlatan Ibrahimovic.
However, Italian outlet Tutto Mercatao claim the Rossoneri face competition from fellow Serie A club Atalanta for the Belgian forward.
Liverpool are said to be monitoring highly-rated Premier League stars Jarrod Bowen and Raphinha following continued doubts over Origi's future.
Edinson Cavani
Manchester United are preparing for the eventuality that Edinson Cavani leaves to join Barcelona, according to the Daily Mail.
The Spanish side are keen to sign the veteran attacker, something that could leave United short.
However Ralf Rangnick's side are considering Erling Haaland, Joao Felix, Timo Werner and Alexander Isak as potential replacements.
Andreas Christensen
Tottenham Hotspur have joined the race to sign the Chelsea defender, according to the Daily Star.
The centre-back is facing an uncertain future with his contract set to expire next summer and no agreement yet in place.
Interest is building with Spurs now in a queue alongside Manchester City and Manchester United to sign the Denmark international.
Rodrygo
Liverpool have put Rodrygo at the top of their summer shopping list, according to El Nacional.
The Real Madrid youngster is regarded as one of the hottest prospects in Europe with the 20-year-old Brazilian putting in some eye-catching displays.
It's claimed that Jurgen Klopp's side are willing to pay €80m (£68m) to get a deal done.
Cristiano Ronaldo
Real Madrid are reportedly monitoring Ronaldo's situation at Manchester United.
Football Insider claim the La Liga giants believe a deal for the 36-year-old could be struck in January following Ralf Rangnick's arrival at Old Trafford.
The report adds that there is a sense that the Portugese star Ronadlo is unsuited to the high-energy pressing game that Rangnick is keen to implement.
Wesley Fofana
Chelsea are reportedly weighing up a possible move for the Leicester and France Under-21 defender.
Goal claim the Foxes star is an option at Stamford Bridge with Antonio Rudiger and Andreas Christensen yet to sign new contracts at the club.
Fofana broke through in terrific style last term but has spent this season on the sidelines after suffering a broken fibula and ankle ligament in a pre-season friendly against Villarreal.
Georginio Wijnaldum
Everton and Newcastle are interested in a move for the former Liverpool star, who could leave Paris Saint-Germain on loan in January, according to 90 Min.
The Dutchman, who spent five years at Anfield following his £25million move from Newcastle in 2016, turned down the offer of a new contract and subsequently joined PSG this summer on a free transfer.
The Netherlands star previously opened up about how he was affected by trolls on social media during his last two years at Anfield, claiming he felt 'unappreciated' by a section of Reds fans.
And he admitted in October he has found life in the French capital tough over his lack of playing time at the Parc des Princes under Mauricio Pochettino.
Eden Hazard
West Ham have seen an audacious £21m bid for the former Chelsea star, 30, rejected by Real Madrid, report Catalan outfit El Nacional.
Hazard joined Madrid in June 2019 but he has endured a number of fitness issues and injuries during his time at the Bernabeu.
Newcastle have also expressed their interest in signing the Belgian forward following the Saudi-led consortium takeover at St James Park.
Casemiro
Chelsea are targeting a move for Real Madrid's Brazil midfielder, according to Catalan outlet El Nacional.
£51m-rated Casemiro, 29, is said to have been on the chopping block at the Bernabeu ever since Carlo Ancelotti returned to the LaLiga giants.
Thomas Tuchel is desperate for midfield reinforcements with Saul Niguez flopping so far since his loan from Atletico Madrid.
Kalvin Phillips
Phillips is reportedly set to snub Manchester United this summer and join Liverpool instead.
The 26-year-old Leeds midfielder is wanted by both clubs in what would be a major summer transfer.
The Sun claim Phillips' loyalty towards Leeds has put him off a move to Old Trafford and now Liverpool will capitalise and bring him to Anfield.
Phillips believes joining Liverpool would better aid his career progression and wouldn't tarnish his reputation at Elland Road.
The England international is under contract at Leeds until June 2024 and is valued at around £60million.
Aaron Ramsey
Everton have reportedly opened talks with Juventus midfielder Ramsey.
Juve are happy to sell the 30-year-old midfielder who has featured just five times for them this season.
According to the Daily Star, Everton have leapfrogged Newcastle in pursuit of the Wales international and are looking to get a deal done in January.
Ramsey moved to Turin on a free transfer in the summer of 2019 after his Arsenal contract expired and has made 49 Serie A appearances in the last two years, scoring five goals.
Ricardo Pepi
Manchester United and Liverpool are reportedly both eyeing moves for American teenage striker Ricardo Pepi.
The 18-year-old has been a hit at FC Dallas in recent months, netting 13 goals in the MLS this term.
The youngster also has three goals in six caps for USA and The Sun claim he is now wanted by two Premier League big guns.
United and Liverpool have sent scouts to watch several Dallas matches and both could be about to launch a move.
Lionel Messi
The Argentine has reportedly begun to question whether Mauricio Pochettino is up to the task of being Paris Saint-Germain manager.
French outlet L'Equipe claim that those closest to Messi fear Poch lacks full control of the PSG dressing room and has lost respect among the senior stars.
Former Barcelona captain Messi is also thought to believe that his compatriot is 'too restrictive' with his tactics that don't suit his play style.
The 34-year-old has managed just one league goal since arriving at PSG in the summer while Pochettino continues to be linked with a Premier League return.
Attila Szalai
Chelsea's move for the Fenerbahce defender Attila Szalai is a 'done deal', amid doubts over the futures of the Blues first-team stars.
Hungary boss Marco Rossi, who included Szalai in all three of his countries Euro 2020 games, was quizzed on which of his players would star in Serie A.
He told Calciomercato: "It's hard to name just one player, but right now I see very well Attila Szalai, who plays for Fenerbahce, but I think he is joining Chelsea.
"Clearly, he has been followed by important clubs in Spain, but apparently his move to Chelsea is a done deal.
"He would be a great player also for Italian football."
Chelsea have a host of defensive options at Stamford Bridge already but Antonio Rudiger Andreas Christensen, and club captain Cesar Azpilicueta will all be out of contract within the next 18 months.
Mohamed Salah
Salah put pressure on Liverpool to resolve his contract situation as he comments on reports linking him with a move to Barcelona.
The superstar forward is entering the final 18 months of his deal at Anfield and would be happy to stay.
