Manchester City boss Pep Guardiola admits Vincent Kompany is among "the best central defenders I have ever seen".

With Kompany off contract in June, Guardiola has made it clear he wants the captain handed a new deal.

"Only Aymeric Laporte has a better left foot than Kompany," said the ex-coach of Barcelona and Bayern Munich. "Every central defender has his qualities, but there is no doubt that Vincent is special.

"His charisma, the winning mentality, the way he does the duels, that's incredible. He is one of the best central defenders I have ever seen. The problem is that he is only there when he is fit."
