Juventus have signed Fiorentina striker Dusan Vlahovic with the deal worth up to a maximum of €80million, making it the biggest transfer of the January window so far.

The 22-year-old, who is the joint-top scorer in Serie A this season with 17 goals, has signed a deal until June 2026 in Turin.

Vlahovic could make his Juve debut when they host mid-table Hellas Verona on 6 February in Serie A.

Fiorentina publicly put Vlahovic up for sale after he refused their offers of a contract extension, with his deal due to expire at the end of next season.

The Serbian also becomes the most expensive January signing ever in Serie A, ahead of AC Milan's purchase of Lucas Paqueta from Flamengo in 2019 for a reported €35million.

Vlahovic became one of the most sought-after young players in Europe during four years in Florence and hit his stride last season as he scored 21 league goals and won the Serie A Best Young Player award.

Tottenham have turned their attention to Juventus forward Dejan Kulusevski in order to try and salvage their January transfer window.

The PA news agency reports that Spurs are trying to sign the 21-year-old Sweden international before Monday night's deadline, possibly on loan with an obligation to buy, after missing out on Porto's Luis Diaz and Wolves' Adama Traore in the last 24 hours.

Kulusevski is known to Tottenham's managing director of football Fabio Paratici, who left Juve in the summer, but has not been a regular for the Serie A side this season, starting only 10 of 20 games in the league.

Yet his versatility in forward areas, where he can play as a winger, striker or an attacking midfielder, will appeal to Paratici and boss Antonio Conte, who has identified a number of positions to strengthen this month.

Conte will be getting anxious over the lack of arrivals, with the deadline just three days away, having made his pleas for reinforcements to maintain their hopes of challenging for the Champions League.

Spurs have also been linked with Fiorentina midfielder Sofyan Amrabat over a possible loan move.

There could still be some outgoings before Monday night as well as Dele Alli, Tanguy Ndombele and Giovani Lo Celso are all free to leave.

Andy Carroll leaves Reading for West Brom

Former Cork City and Sligo Rovers midfielder Kieran Sadlier has signed for League 1 side Bolton Wanderers.

The former Ireland Under-21 international has spent the last four seasons in England with Doncaster Rovers and more recently Rotherham United.

West Brom have confirmed the signing of Andy Carroll on a free transfer until the end of the season.

The 33-year-old striker, a free agent after his deal at Reading ended earlier this month, is eligible to play against Millwall on Saturday.

Albion have moved for the former Liverpool and Newcastle player after Daryl Dike suffered a hamstring injury on his full debut against Peterborough which will rule him out for eight weeks.

Dike only moved to the Hawthorns from Orlando City for #7million at the start of the month.

Baggies head coach Valerien Ismael told the club's official website: "Andy is a player who is able to help us straight away.

"He is ready and brings with him all the attributes we need. It could be a win-win situation for us."
