Rovers fans who greeted his arrival with scepticism have now taken him to their hearts.
Allardyce, who also got the best out of him at Bolton, said: "I've talked to him about the stuff he has to be careful of.
"People will look out for him because he portrays himself in this image with stand-out clothes.
"He has some of the worst gear you've ever seen in your life. You can't miss him from three miles away with some of the colours.
"Then there's the big chains, big belts and big blond hair.
"He got a little bit carried away but he has settled down now and long may it continue.
"I wouldn't say he's scared of me. I think he respects me and I respect his ability. If he gets into trouble he gets punished like everybody else.
"We've spent a lot of time on making sure he tries to get rid of that image he had before. He's never going to lose it completely, there's no danger about that. But he hasn't got himself into any trouble for many a year now, both on and off the field."
