Paris Saint-Germain are interested in signing Chelsea striker Romelu Lukaku, according to reports.
The Belgium international, 28, recently told Italian reporters he was "not happy" at Stamford Bridge and questioned manager Thomas Tuchel's tactics.
Lukaku was dropped for his comments but has since apologised and is now back in the team, scoring against Chesterfield in the FA Cup on Saturday.
But according to Catalan outlet El Nacional,Tuchel and Blues owner Roman Abramovich are still considering selling Lukaku.
That's reportedly put PSG on "red alert", as the French giants are in danger of losing their star striker Kylian Mbappe.
Should Chelsea sell Romelu Lukaku after his controversial interview? Let us know in the comments below!
The Frenchman, 22, is out of contract at the end of the season and is expected to join Real Madrid on a free transfer.
PSG will be identifying Mbappe's replacement over the coming months and Lukaku could be the perfect option.
The club's owner Nasser Al-Khelaifi is thought to be a fan of the former Manchester United ace and it would be a solid investment considering his age and record.
Lukaku has scored 198 goals in 410 league appearances since making his debut for Belgian outfit Anderlecht in May 2009.
It's believed PSG are willing to spend €90million - around £75.5m - on Lukaku, despite Chelsea paying Inter Milan £97.5m for his services last summer.
Cristiano Ronaldo is thought to be another candidate to replace Mbappe - linking up with rival Lionel Messi - but would only be a short-term option. He turns 37 next month.
PSG are unlikely to make a move for their next striker until the summer, giving Lukaku the chance to rebuild trust with Blues supporters.
Mbappe has already confirmed he won't be leaving the Ligue 1 hopefuls in January, as he bids to win his first Champions League crown.
"I will give everything I have to win the Champions League, the league and the cup," the World Cup winner told CNN. "And to give all the pleasure to the fans, because they deserve it.
"I was honest [when I said I wanted to leave]. I gave a feeling, I gave what I have in my heart. I'm happy to stay... It's my city too. I'm French... I want to win everything this season.
"Paris is my city, it's where I was born, it's where I grew up. To play for PSG, it's an amazing feeling to play with your family and friends alongside of you."
Speaking to Chelsea fans earlier this month, Lukaku said: "I'm sorry for the upset I caused. You guys know the connection I've had with this club since my teenage years.
"I totally understand you guys being upset. It's up to me to restore your trust now. I will do my best, show commitment every day on the training ground and in the games to make sure we win."
On his future, Lukaku added: "I came when I was 18, it didn't go so well, now I am back here at 28, I think, the prime years of my career. I can't mess this up.
"I worked really hard for the last 10 years to get this opportunity, I'm really happy to be here. I have to show my commitment to the fans, to make sure we win games and a lot of trophies at the end of the season."
