Far to early for that.
He is 18. Only broke through around Christmas last year, playing 791 minutes in total (90 minutes only once).

He has never been a mainstay in that team. Never been a regular starter. To expect that to have changed over the summer would be a mistake, IMO.
The Championship is 4 games old. There are many more to come. And once the fixtures start piling up players like Clarke will get chances.
And lets be honest, he has far more chance of playing football there than here this season.
To have him training and playing under Biesla this season could prove to be a godsend by the time he comes back.
