New Manchester United signing Alexis Sanchez believes that he will be playing with the best goalkeeper in the world in David de Gea.

The news of United's new signing is official, with Sanchez coming from Arsenal and Henrikh Mkhitaryan going in the opposite direction.

Such straight swaps are rare, but the two clubs managed to agree a deal that did not involve any exchange of cash. The two 29-year-old players will now play for their new clubs from the weekend onward.

Asked about his new teammates, and whether he knows any of them from before, Sanchez had the following to say: "I've not had the chance to get to know them personally or spend time with any of my team-mates up to now, but of course I know them from having played against them in the past," he said.

"I believe that David De Gea is one of the best goalkeepers in the world right now. He's a player who I've always found it hard to score past, and so for me he is right up there with the best keepers in the world."
