Chelsea have confirmed the signing of goalkeeper Emi Martinez from Aston Villa.The Athletic reported on Thursday that the two sides had agreed a deal worth £7.5million for the Argentina international, who has signed a two-year contract at Stamford Bridge, with the option to extend by a further 12 months.The 33-year-old was offered to Chelsea by his representatives, as reported by The Athletic on Wednesday, after a proposed move to Juventus broke down earlier in August.“I’m delighted to be at this football club,” Martinez said in a Chelsea release on Sunday morning. “Coming to Chelsea, for me and my family, was an easy decision to make and I’m just over the moon — I can’t wait to get started.“I want to be successful here. I’m someone who wants to win at everything I do and I want to bring that here to this football club because it’s a football club that wins titles, so I think it’s a good match.”Why Xabi Alonso’s Chelsea will be differentJJ BullVilla moved quickly to sign 24-year-old goalkeeper Zion Suzuki from Parma as their new No 1, with Martinez — who made 256 appearances for the club and was key in their success under Unai Emery — training alone thereafter.Chelsea’s move for Martinez followed a pair of mistakes from Robert Sanchez in their season-opening 3-2 victory against Fulham on Monday.The west London club were entering their fourth season with the 28-year-old Spaniard as their starting goalkeeper, and his appearance at Craven Cottage was his 112th since joining from Brighton & Hove Albion in 2023.
