Olivier Giroud insists he's learned to live with his critics.

The former Chelsea striker addressed the doubters at his AC Milan media presentation this week.

He said: "There's always critics, I don't think there's any athlete who gets 100% support from everyone. It's something you have to deal with every day, I rely on my mental strength to try to turn criticism into positive energy.

"It's true, I've often heard that I'm underrated, but I don't need to read the newspapers or look at social media to know if I've played well. To do that I just have to listen to those close to me; my goal at AC Milan is to do well and make the fans happy."

Giroud also revealed: "I would like to contribute by helping the youngsters in this team to grow and express their potential. I would like to be a kind of big brother to them, it's something I did at Arsenal and Chelsea too. 'No pain no gain' is my philosophy, if you don't suffer you can't play.

"People remember you as a great footballer but above all as a nice person. That's why I want to bring great professionalism to the team. I will give my best and try to get the most out of my teammates, like Ibra does, he's very demanding of himself and his teammates. I think that's the right attitude not just in sport, but also in life, and it's something I will try to bring to this team".
