Chelsea boss Jose Mourinho has hailed the "unbelievable" strength of Manchester City's squad.

The Blues go head to head with Manuel Pellegrini's side on Sunday, and the Portuguese coach has said that City have a strong enough squad to field two top teams.

"Pellegrini can do well in England and he has the most important thing, which is an unbelievable squad of players," the Daily Mail quotes Mourinho as saying.

"[City have] a fantastic squad and fantastic players, a really good team.

"They are a very good team, they have two very good teams. One playing and another one on the bench and in the stands."

Mourinho's side are currently second in the Premier League.
