Hi bro, well will we say it's so much of fatigue? I don't think so. The guys that needed to improve were rested. OK see the following culled from my live post:

"A few talking points:

It was not that Leeds' pressing game was something Arsenal isn't used to, but their failing was their unsatisfactory ball handling. They needed to be more intelligent when in possession.

The major culprits in the point above were the two Gabriel's– the striker keeps holding on to the ball(to dribble) for far too long for such a match where Arsenal was under pressure; the defender, as always(even last season) is not an assured fellow on the ball,when push comes to shove. Even the impressive Martinelli also was not helping matters at times holding unto the ball so much and being crowded out. Captain,Martin Ødegaard couldn't find solutions in that kind of frantic game.

Beautiful to see Arteta haul out the captain early enough, to allow the midfield maestro, Fabio Vieira, work his magic. But the faltering guys mentioned above made his work difficult. Finally and correctly Gabriel Jesus was taken off.

You need to credit Arteta for inviting Holding from the bench,to change shape to a back three(or five) once Jesus was taken off to give Leeds a more difficult route to the goal. It wasn't the only option in that circumstance, but it was a sensible, smart option.

You can't but notice that eventhough this was not the usual vintage Arsenal attacking performance, it was a master-class in how to position yourself without the ball. The boys are so well drilled on what to do or where to go without the ball(with a leader like Xhaka offering calm, that someone like me was confident they would see the match through."

My post has more on that match.

Then @samostically great times are here, at the very least it has been proclaimed ARSENAL FAITHFULS GO AND SLLEP,CHAMPIONS LEAGUE IS SURE. In that post you would notice that there is league title talk even.

Cheers
