He will, and i think a few of Sunderlands players, will struggle with the physicality of the Premier League (Its why Jobe hotfooted it off to Germany).
That's not a slight on him, he's 18, but i can see him being used a little less next season for his own benefit
We saw it last season with Ipswich, when good technical footballers like Davies, Hutchison, Clarke, all struggled a bit, and the more physical players such as Delap, Greaves, and Burns & Szmodics (when fit) looked more at home.
A team can carry 2 or 3 of these, but Sunderland have O'Nein, Hume, Cirkin, Rigg, Neil all lacking in physicality. I think Neil might be able to put it on, but that will still take time to adapt.
Thought Greaves struggled if im honest mate.
