Transfer rumours: Kostic to Juventus, Muriel to Newcastle, Sanchez to Marseille

The 29-year-old had been linked with a move to West Ham United, but the Hammers failed with a £12.6m (€15m) bid including add-ons and have since swooped for Mawel Cornet from Burnley.

According to journalist Fabrizio Romano, Juve have agreed a deal to sign Kostic for an initial €16m (£13.5m) plus add-ons and the winger will soon fly to Turin to undergo his medical.

The Serbia international has been identified by head coach Massimiliano Allegri as a priority target, and he is now set to sign a long-term contract with the Serie A giants.

Europa League holders Frankfurt have confirmed that Kostic will not fly with the rest of the first-team squad to Helsinki for their UEFA Super Cup clash with Real Madrid on Wednesday.

Kostic has been a key creative outlet for the German outfit, providing 64 assists since joining the club in August 2018.

Staying in Serie A, Atalanta BC striker Luis Muriel is reportedly attracting interest from Premier League side Newcastle United.

Eddie Howe is yet to recruit an attack-minded player in the summer window and has seen two bid for playmaker James Maddison rejected by Leicester City.

However, TUTTOmercatoWEB claims that the Magpies have made contract with Atalanta over a proposed move for Colombia international Muriel.

The 31-year-old faces an uncertain future with the Italian side as he has entered the final year of his contract.

Muriel, who has also been linked with Juventus, has been prolific for Atalanta since joining the club in 2019, recording 49 goals and 19 assists in 97 Serie A appearances.

Meanwhile, free agent Alexis Sanchez is reportedly closing in on a move to Ligue 1 side Marseille.

The 33-year-old forward is without a club after Inter Milan confirmed on Monday that they had mutually agreed to terminate his contract.

Journalist Fabrizio Romano now reports that Sanchez is set to complete a move Marseille next week and will sign a two-year deal until the summer of 2024.

The Chile international leaves Inter after scoring 20 goals and providing 23 assists in 108 appearances across all competitions, as well as winning three major honours including the 2020-21 Serie A title.

Marseille have already enjoyed a busy summer window and Sanchez is set to become their 12th signing after the arrivals of Pau Lopez, Matteo Guendouzi, Jordan Veretout, Luis Suarez, Cengiz Under, Arkadiusz Milik, Jonathan Clauss, Isaak Toure, Chancel Mbemba, Nuno Tavares and Ruben Blanco.

Elsewhere, Borussia Dortmund have completed the signing of striker Anthony Modeste from FC Koln for around £4.2m.

The 34-year-old has penned a one-year deal with the Bundesliga giants who have moved for the Frenchman after summer signing Sebastien Haller was diagnosed with a malignant testicular tumour last month.

Speaking to BVB's official website, sporting director Sebastian Kehl said: "After our analysis of last season, we made a conscious decision to recruit a classic centre-forward who could bolster our offensive game by offering physicality, a strong aerial presence and a goal threat.

"In light of Sebastien Haller's illness, we are glad that, in Anthony Modeste, we have been able to add another striker with this profile to our squad for the current season.

"He is a seasoned pro who knows the Bundesliga very well, who scored 20 goals last season and who, with his skillset, can fill the exact role that our coach Edin Terzic envisages for the BVB style of football."

Modeste, who will wear the No.20 shirt, leaves Koln after scoring 79 goals and registering 10 assists in 156 appearances for the club in all tournaments.
