Here's a bit more - the more said, the more it seems in context e.g Moyes qualifies what he says without it sounding so harsh...
Moyesy said: "He's had a lot of niggles. He's nearly not quite adapted to what the Premier League means and how the games go.
"I look at him and he's signalling to me with 15 minutes to go - so maybe he's not quite got what's required at Everton or the Premier League.
"What he has got in abundance though is pace, ability, he can score goals, he can take you on and he can play in two or three different positions.
"But we're finding that we're getting 60 or 70 minutes into games and thinking will he keep going? Will he pick up an injury? Will he lose concentration?
"His ability is not in question but there are a lot of players who can take time to get used to the Premier League.
"He missed three months through the middle, so he's had a bit at the start and now at the end. So maybe he's not quite got up to match speed all the time and we may have to deal with it to the end of the season.
"When you stay at Everton for a time it gets you used to it. Look at how Marouane Fellaini has recently played with injuries, look at Phil Jagielka and Tim Howard.
"That mentality grows on you when you have been here a while, so when you're new to it maybe he's not aware that's what you do at Everton.
"Because we don't have the numbers, or in some cases the quality at times, when we can say 'Don't worry you can come out because we've got someone to replace you'.
"We need people to play in two or three positions which he can do - but quite often you have to go out there when you're not always at 100 per cent."
