James Trafford, currently with Manchester City , is the latest name linked with a potential switch to Chelsea. The goalkeeper could become a key signing should the move materialise, as the club seeks to strengthen in a key area of the pitch. Chelsea remain optimistic, but the deal is not without hurdles. West Ham, Leeds and Tottenham continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. With only 34 goals conceded in 29 (1.17 per game), Chelsea have been one of the stronger defences in the Premier League this season.. James Trafford would be asked to keep that standard and provide dependable cover when needed. Manchester City continue to be linked with Felix Nmecha, Joao Neves and Jack Hinshelwood while Chelsea are also rumoured to be tracking Darwin Nunez, Aleksandar Pavlovic and Aurelien Tchouameni.
