When he's able to play at his own pace you can see why Pep rated him in the first place, he creates goals for fun. I don't think he will be able to do that against many of the top teams unless he can make that adjustment for the pace of the PL(not every player can) but I think he needed these couple of games to remind himself and everyone else, he does belong at the top in some capacity.
No matter the opposition, there's not many players around who could do the numbers he's done(with the same quality) in the past few games.
