History is not being rewritten. His issues have been evident for many a season, you can go back to the champions league knockout we played in, and many other games big or small to see his flaws (incidentally when playing in his best position rather than his current one).
Yes, he has had great moments with United playing on the counter, with ball carrying attackers in front of him running into open space for him to supply with his superb vision.
That approach only takes you so far though, when space is more limited or against a better level of opposition, you would want a player who can ally that vision to close control and the ability to resist the press, play on the turn and carry the ball to open up defensive lines. He lacks those qualities - as do many of our players in his time here so far.
