The thing I like to remember about Roberts is that he played in an FA Youth Cup tie away at Manchester United and a certain Mason Greenwood didn't get a sniff. I don't know what happened at Rochdale but he wasn't exactly surrounded by good players, they struggled with him in the side and without him
My guess would be going on loan again in January.
Now the club has 250 minutes of Roberts playing games against PL/Championship opposition that they can show to Championship clubs and he did well so there will be more interest in him compared to what was probably the case in the summer after the not so great Rochdale year.
