Manchester City boss Manuel Pellegrini is delighted with the way Joe Hart has responded to the arrival of Willy Caballero.
Hart has responded to the challenge from the Argentinian by producing some fine displays and Pellegrini is pleased with the current situation.
The Chilean said: "Joe is having a very good season. The arrival of Willy Caballero was very important for the club, for Joe, for Willy, for everyone - because he is a very good goalkeeper.
"I think the best way for players to have high performance is when they have important competition. I think that was very useful for him and I am very happy about that."
