I think he found it difficult at Rochdale and had a problem coping with big CFs
Yes, but he had a much bigger problem playing in a very poor Rochdale team which got relegated.
As well as Roberts, we now have several players in limbo-land between the U23s and the 1st. team (Richards, Caicedo, Khadra if he doesn't go on loan, Karbownik, for example). Loans are a possibility - but if they stay 'at home' this season, playing in the cups and mainly bench-warming, they're all eligible (I think) for the EFL Trophy. A mickey mouse trophy, yes, I know, but we're remarkably short of trophies - but it woukd be fantastic if we could have a day out at Wembley and become the first PL2 club to win (or even get very far) that competition!
