​Manchester United have signed veteran goalkeeper Karl Darlow from rivals Leeds on a free transfer.The 35-year-old Wales international turned down the offer of a new deal at Elland Road and has instead signed a two-year contract with the option for a further 12 months at Old Trafford, where he will serve as Senne Lammens’ back-up.AdvertisementAdvertisementAdvertisement“I am extremely proud to sign for Manchester United,” Darlow said in a United statement on Tuesday. “I’m joining an excellent group of goalkeepers and I’m really looking forward to all pushing each other to ensure that we maintain the highest standards, which this club demands.“This is a really special opportunity; everyone can see what an exciting time it is for the club and I cannot wait to play my part in supporting my team mates and helping to drive the group forwards.”Darlow’s arrival comes as Lammens’ current back-up Altay Bayindir is expected to leave United, having been linked with a return to his native Turkey. Veteran Tom Heaton, 40, signed a new one-year deal earlier this close season.Darlow joined Leeds ahead of the 2023-24 season and made 38 appearances for the Whites, 22 of them in the Premier League.A Leeds statement said: “Thank you Karl for your dedicated service to Leeds, we wish you and your family the best for the future.”
