I'm sure he will be used, I'm just not convinced he's ready for a Premier League start with only a slightly rusty-looking (and understandably so) 75 minutes against a mid-table League Two side under his belt after being out for 2 months.
I'm sure he will be too - just saying that at £14M he's got to be a first choice for the first team very soon, if not straight away (although I do realise that our previous record signing spent a while kicking his heels too).
