"It's always good and important to start with a win in a new season," he told Manchester City's official website.
"We knew it would be a tough but we gave everything – we started from the first minute, being aggressive and trying to score and I think we deserved the win.
"I'm very proud that we managed to win this game. First games can be tough but we did it again and I want to thank our fans because I thought they were brilliant today, once again."
