Those who can't make their mind up about the Arsenal boss are once again singing his praises.
Arsenal's 3-0 win in Olympiakos was impressive to say the least.
The team and the manager did themselves proud to dig themselves out of a hole. But how many times have Arsenal found themselves in a hole in recent years?
Indeed, with the team at the north London side's disposal, they never seem to do things the easy way. And it almost feels like Arsene Wenger does it on purpose.
Arsenal always lower expectations - rule themselves out of a title race, give themselves a near-impossible task in the Champions League and the like - so that they can dig their way out of trouble and see Wenger get the plaudits once again.
But, if the Frenchman was truly doing a good job, would Arsenal be in a bad position in the first place?
Wenger famously rested Petr Cech in Europe as the Gunners faltered, while even Arsenal's FA Cup wins have come after all hope of winning anything else has been extinguished.
Public opinion falls, faith in Wenger dwindles and - boom - the north London side pull a rabbit out of the hat.
If the Arsenal boss was doing a good, steady job in the first place, though, there wouldn't be any need for magic tricks. So, for those once again lauding the 66-year-old, remember that it was some of his decisions that almost knocked the Gunners out of the Champions League in the first place.
And there will be more disappointments to come - before another unique performance makes everyone forget them all over again.
