To be honest, under Flick, he has looked a player every time he got a chance. Should have played a little bit more with a little more trust.
He is still only 21 (well 22 in a few days) so I reckon the Flick will want him to stay and he should get more chances next season if he keeps on plugging.
Think we'll see his minutes grow more as we have many home games against not great teams in La Liga and many difficult games in CL + copa semifinal 2nd leg vs Atletico.
Think his main problem is he's really physically weak. Very good technique and all, but easily barged of the ball without effort. Pedri is kinda of midget too, but really sturdy goblin in comparison.
