Emilano Martinez, currently with Aston Villa, is the latest name linked with a potential switch to Man Utd in multiple papers and online sources. The goalkeeper could become a key signing should the move materialise, as the club seeks to strengthen in a key area of the pitch. Man Utd remain optimistic, but the deal is not without hurdles. Chelsea and Paris SG continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. So far in this season, Man Utd are conceding 1.83 goals a game (11 in 6), more than they'd like compared to the Premier League standard. The hope is Emilano Martinez adds a bit of steel and helps make them tougher to break down. Aston Villa have also been linked with Kang In Lee, Wilson Isidor and Julian Brandt while Man Utd are reportedly monitoring Raphinha, Marc-Andre ter Stegen and Etta Eyong.
