Former Manchester United coach Phil Neville says they must do all they can to keep hold of David de Gea. With a new deal yet to be agreed, De Gea continues to be linked with Real Madrid.
"The biggest thing is David De Gea, and keeping him at the football club," Neville told the Manchester Evening News.
"From when he first came, to how he is now, I don't think I've seen a player develop and improve as quickly as him.
"I saw with Cristiano (Ronaldo), I saw the development in terms of his performance, his size, his stature and his physique.
"He's winning football games on his own. Last minutes saves against Everton, Hull, Arsenal away - there's seven or eight occasions where he has won United games which just shows you that he is world-class."
