Ander Herrera believes that David De Gea will remain professional at Manchester United despite failing to earn his dream move to Real Madrid.

The De Gea transfer saga turned into a fiasco as United and Real Madrid were unable to conclude a deal for the goalkeeper in time during transfer deadline day. Herrera said: "David is my friend and I want the best for him. He has had a very, very good four years for United and he will do it again. He is a very good professional, you can see that every day, he never missed one training session, he never missed (attending) one game.

"So I think he is going to do it again. For me, he is the best goalkeeper in the world and I think the same for many people. We are happy as a team to have him with us and as a friend I am happy also."
