More time working on his fitness? He's not back from a long term injury or just a kid. If he's not fit enough to play professional football then he should be ashamed. There is no more time. He doesn't want to get fit, he doesn't want to do the defensive work and his decision making and so his output are poor.
two seasons of playing for a manager who doesn't want you to defend and - bizarrely for a physio - wasn't arsed about player fitness
with one season in between playing for a manager who didn't really like him
and then half a season with a manager who wasn't interested in you, before then going out on loan and finding a manager who liked you, so you play well and work on your fitness
I'm not saying he needs it now, I'm saying he needed it at Everton. He became demotivated. it's a shame. he's boss.
