Him and Alli are different players, Alli is more gungho buccaneer type midfielder, his game is more built around energy.
Ross is a very rare type of midfielder for England, his control and skill level, the way he glides around the pitch, is 2nd to none, he's come on so much this season, his goals scored and assists are much improved, he links play very well now too.
Alli and Barkley are a very good blend for that England midfield, with Dier sat behind them it's looking very very good for the next decade.
