Rio Ferdinand believes Manchester United have made a big mistake by failing to agree a deal with Borussia Dortmund to sign Jason Sancho this summer, after suggesting they are spurning the chance to sign a player who could become "the best in the world" over the next decade.
Dortmund announced on Monday that they will not consider any more offers for Sancho in this transfer window, after United failed to meet their deadline to pay their €120 million (£108m/$142m) asking price despite lengthy negotiations.
Manchester United, meanwhile, are refusing to give up hope despite Dortmund's statement, although the Red Devils have been left frustrated by negotiations.
