He has very good strengths, just has some glaring weaknesses as well. Was good making some plays, tackles, going forward, and holding it at times. But also a bystander on some of their attacks, and needless turnovers/losing the ball rather than passing at times.
The stuff he does well 100% translates to the PL, and if he only did that he could be a very good player. The question will be if he can fix the other half of his game. Because of that the most pressing need is someone better at his spot.
