Fernando Muslera to Chelsea

Premier League leaders Chelsea have reignited their interest in Galatasaray goalkeeper Fernando Muslera, according to the Daily Mail.

The Blues are hunting for a replacement back-up keeper, with current second-choice keeper Asmir Begovic expected to leave Stamford Bridge in the summer.

Boss Antonio Conte had previously been linked with AC Milan's Diego Lopez, who is currently on loan at Espanyol, and Paris Saint-Germain's Salvatore Sirigu, who's on loan at Osasuna. However, Chelsea's former first-team goalkeeping coach Christophe Lollichon has recommended Muslera to the Blues.

Berkay Ozcan to Arsenal

Arsenal are keeping tabs on Stuttgart's 19-year-old midfielder Berkay Ozcan with a view to signing the player in the summer, according to his agent.

The Turkish playmaker has scored twice and provided three assists in 2.Bundesliga so far this term, and his performances for Die Roten have impressed the Gunners.

Thomas Muller to Manchester United

Thomas Muller is the latest striker to be linked with a switch to Manchester United in the summer, with the Bayern Munich man thought to be keen on the move, according to Spanish newspaper Mundo Deportivo.

The 27-year-old hasn't impressed boss Carlo Ancelotti this season, finding the net just once in the league from 21 appearances, and the paper reports that Muller is interested in linking up with Jose Mourinho.

Andrea Belotti to Barcelona

TalkSPORT are reporting that Barcelona have taken the lead in the race to sign Torino's prolific young striker Andrea Belotti, with the club holding "secret talks" over a potential summer transfer.

Arsenal, Chelsea and Manchester United have all been linked with the 23-year-old, who has scored 22 goals in Serie A this season, but the Italian has reportedly always dreamt of playing for the Catalan side.

Anderson Talisca to Liverpool

Liverpool have emerged as contenders for the signature of Benfica's Brazilian forward Anderson Talisca.

The 23-year-old is currently on loan at Turkish Super Lig side Besiktas, scoring eight goals and providing three assists, but Chelsea and Serie A side Lazio are also thought to be keen on the player's services.
