In terms of off-field problems, does he? There was the domestic abuse case for which he wasn’t convicted but that was a few years ago now. Given that a court ruled him as not guilty (IIRC, I am sure it went to court), it’s difficult for us to hold that against him. It’s quite possible that he’s grown up now.
To be honest, I don’t particularly like the guy, but I only have to watch him play football, not go for a beer with him. My main issues would be that he’s not very good and has knees like glass.
