Manchester City manager Roberto Mancini has insisted that he is "happy" with controversial striker Mario Balotelli, despite the Italy international not performing in the 3-0 win over Sunderland yesterday.

Mancini did admit however that Balotelli, who stormed down the tunnel after being substituted, "can do better".

"Mario worked a lot, he had a chance, I am happy with Mario," The Sun quotes Mancini as saying. "Mario played a good game but I think he can do better.

"When Sergio [Aguero] came on he was fantastic. He's scored one goal, he had another chance and played very well."

City are currently second in the Premier League, four points behind leaders Chelsea.
