2 year loan deal with Celtic.
We can't recall him 'till the end of next season. He was in & around the first team squad for long enough last season to judge that. My guess that we've made the decision already
18 months loan.
Quite likely Roberts' future will be in the middle of the pitch anyway.
Also he was injured for most of the time he was with the first team squad last season, and it was under Pellegrini so I'm not sure how relevant it is anymore.
