Jose Mourinho believes he got his tactics right in the second half of Chelsea's 3-0 loss to Manchester City.

The Portuguese opted to replace captain John Terry with Kurt Zouma at half-time, later revealing to Sky Sports that the move was made in a bid to keep City's attack - in particular Sergio Aguero - quiet.

Reigning champions Chelsea were eventually beaten by three goals after trailing 1-0 at half-time but Mourinho felt his tactical alteration was the right one to make.

"It was just a decision," Mourinho said.

"I know that Zouma is the fastest defender we have in the squad. In that moment Manchester City were going to play counter-attacking.

"I knew they were going to play long balls to Sergio Aguero. Zouma is a different player to John Terry and Gary Cahill.

"It was proven completely right because Zouma was completely in control."

Aguero opened the scoring for City in the 31st minute before second-half goals from Vincent Kompany and Fernandinho wrapped up the victory for Manuel Pellegrini's men at Etihad Stadium.
