Charles N'Zogbia admits he's happy playing for Aston Villa manager Paul Lambert.

Last season, the Frenchman infamously tweeted after a match against former club Newcastle just over a year ago that "for the first time in my life I'm not happy playing football."

He told the Express & Star: "All I have to do is accept his decisions and work hard in training.

"For me that (last season) was another time in the past. I am a guy who can really look forward into things and forget about things in the past. For me it was a bad time and I maybe wasn't happy but now I am happy.

"It (the tweet) was maybe a mistake but everybody can have a bad day and it happens. It's all about the way you are going to react the next day and that's it."
