Firstly there's this
So let's recap,
Leaves United, takes a pay cut to play for Everton in order to start more games and get his game for Ireland. Plays really well finishes higher than anyone else in the squad in the PL and still doesn't get picked.
He fucked off because he knew he was never getting picked so why bother. He's a legendary moan according to everyone at Everton so it's not that surprising. There's two of them in it, He shouldn't have said fuck this I'm off but lets not forget how mental Trap was. So, yeah on one hand fuck him.
On the other hand if he starts in the holding role along side McCarthy with Brady, Hoolihan, Pilkington etc playing in front of them and we win games well enough, all will soon be forgiven fairly quickly. Football is a fickle game after all.
If I was manager I wouldn't pick him on principal, on the other hand if he plays as well this season as he did last it'd be hard not to.
If he and Trap had had a row I'd have said fair enough they can't/don't get on and with Trap gone then the way is clear. But it doesn't seem to have played out that way, he just comes across as a bit of a spoiled brat.
