This apllies to all players.
All players ever, generally, for all clubs? Because if that's what you're saying that's simply not true.
If you meant for Barcelona while he's been at the club, then yea but that's doesn't say anything for him or against my point.
He plays well, when for whatever reason the team is on point and in full gear, and it's not because of him as we've played many good games without him over the years.
Their is a couple of games where we played poor and he provided an assist but we can say that for all our midfielders/players, so that point is mute.
