Stiliyan Petrov is not surprised to hear about former Aston Villa team-mate Gabby Agbonlahor's off-field behaviour.

The club captain has been suspended pending an internal investigation following newspaper allegations that he used the legal high nitrous oxide after he was pictured partying just hours after Villa were relegated from the Premier League.

This incident comes a couple of weeks after another club investigation into his behaviour while in Dubai where he was seen smoking a shisha pipe.

"That is Gabby's type of life all these years, even when he was outstanding, when he was bad. He loves the club, he is always out there, he wants to perform," Petrov said.

"Gabby is different and I don't think it is Gabby's fault what is happening. Yes, he is part of it, he should have dealt and acted better but I certainly think that is not the first time Gabby smoked shisha, that he has been out and had a couple of drinks, partying. Everybody does it."
