"People don’t understand tiredness very well in England sometimes. They think you can only be tired at end of the season,” Wenger was quoted by Arsenal.com ahead of tonight’s Champions League match away to Olympiakos.

Like everything with Wenger now it's a self-fulfilling prophecy. He announces the excuses in advance, then sounds disappointed afterwards.

An ultra-motivator like Klopp or even Mourinho would be announcing before the game that the fringe players will be motivated by gettin a chance and so determined to impress that they would be able to overome any potential tiredness or lack of sharpness. Their hunger would overome any physical issues.
