Chelsea have reportedly identified Leeds United winger Raphinha as a potential transfer target.
The 25-year-old is enjoying another strong campaign at Elland Road, contributing eight goals and two assists from his 19 Premier League appearances.
Raphinha has allegedly been targeted by West Ham United, who have been informed that the playmaker is not for sale before the end of the month.
However, according to transfer expert Gianluigi Longari, Chelsea are ready to join the race to sign the Brazil international.
Blues head coach Thomas Tuchel is said to be contemplating an approach at the end of the season when Raphinha will have two years left on his contract.
Leeds, who will try to tempt the player into penning fresh terms, are unlikely to consider any bids below £50m.
