Portsmouth fullback Glen Johnson says former club Chelsea are a stronger team under Luiz Felipe Scolari than they were with Jose Mourinho.

Johnson said: "Obviously they were a fantastic side when I was there, but they seem to have improved even more under Scolari.

"They've taken their game to another level.

"I've heard a lot of good things about Scolari, the lads really like him.

"They have some fantastic players and their movement is frightening. Without a doubt, they are the team to beat this season."
