This is exactly my point. The match against Dortmund, a couple against Real Madrid, and Liverpool in a cup final. Even ignoring the goals scored his performances in those matches were great with the ball. But we are talking here about one or two games per season where he put everything together. You can’t put one off matches as the barometer when for large parts of those seasons, game to game his technique in general play was sloppy and nothing like the matches mentioned.
Just because he played as a false 9 doesn’t mean he was battling defenders all game, he dropped deep and drifted plenty and still lost the ball, slowed down attacks, or had a general unawareness of what was around him A LOT of the time. It doesn’t help that his ability to dribble out of pressure or 1v1 was pretty much non existent aswell.
If he performed like he did in those matches for only 30% of the time he was here I would agree with you that there is something there. But the sample size is so small that I just can’t.
