Man Utd legend Neville: Di Maria the right signing
"He can run and Manchester United haven't got any pace in wide areas," said Neville, speaking to Sky Sports. "It is incredible.
"That is what the club has been built on for the last 10 to 15 years - being able to get from box to box quickly, being able to spring on teams, having people that can dribble and are quick in the final third.
"They have Adnan Januzaj but they really have lost that variety."
He added: "The fans say a central midfielder or a centre-back is needed more, but I don't see any difference with a winger in that they need all three.
"This is the first part of that - the correct signing, if they can get him."
