When Mesut Ozil signed for Arsenal there were delirious scenes as fans gathered outside The Emirates.
And sure enough, the same season the club's trophy drought ended, but the German was only a bit-part player in the FA Cup triumph, with his 2013/14 season disappointing from a personal perspective.
This year started off woefully too, and despite improvement which last week saw his statistics compare favourably to Chelsea's Oscar, his season may have taken a disastrous turn last night.
A big performance was not just expected against Monaco in the Champions League, it was demanded.
As the club's record signing at £42 million, there is only so much flattering to deceive which fans can put up with. Against a team considered beatable, Arsenal flopped, and Ozil was unable to influence the game.
It was not through lack of effort. Ozil tried, and he ran, but the quality and the control was not there. The game did not flow through him as he would like when he is at his best, and he did not manage a single shot at goal.
No shots can be forgiven if he is providing for others, but he managed only one key pass, and one dribble. Defensively, there was just one tackle, no interceptions, and a booking.
A match winning and qualification turning performance in the second leg can re-write his early legacy at Arsenal, but there was no evidence on the basis of the game at The Emirates that he will live up to his billing as one of the best playmakers in the world.
Here's a look at how fans reacted on Twitter to his display...
Is it that Ozil is the most over rated 'world class player' or the overrated manager is making the sqaud under perform. I say BOTH #AFC— Doublegooner (@Doublegooner) February 25, 2015
Ozil played so bad tonight, too emotional and missed many passes, #AFC— Ulil Abshor (@ulilabshorramad) February 25, 2015
I also hate to slate certain players but Mertesacker and Ozil were Sunday league quality tonight. Simply not good enough. #afc— JY (@JonnyUppingham) February 25, 2015
Remember when we signed Ozil & thought he was the best thing since sliced bread?? #AFC— Mike Hall (@mhallscouse) February 25, 2015
