The way he treated Morten Gamst-Pedersen in a game against Blackburn last season was disgusting. Morten seems to be a genuinely nice guy and for his trouble he got a dig in the ribs from Joey. After Morten dared complain about this Joey proceeded to continously cup his balls in his hand and spout vile abuse at Morten. Classy.
Maybe he has grown up since he was good enough to take Gamst-Pedersen out for a meal afterwards to apologise. Dinner with Barton - that's an invitation I'd find hard to refuse!
