I don't know any 22 year olds who dominate games consistently. But I've seen him be by far the best player on the pitch vs Liverpool (more than once) and play brilliantly vs the likes of PSG & Atletico Madrid in the CL. He steps up on big occasions regularly.
He's still got plenty to work on. International football can be a rude awakening stylistically, especially under someone like Southgate. But he's hugely talented and a pleasure to watch play football, he may not be the most explosive/productive, but like B.Silva he makes the game look easy.
