Panda this is part of the reason I think Arteta was so bullish about Saka getting used to 3 games a week last season. Wenger said something similar in the last week or so too. We can't get to this stage of the season and start pissing our pants cos the lads have to play three games in a week. Arteta has good rotation options for most of our players, save for Saka and Odegaard really (and Martin seems like he's a bit of a Forest Gump in regard to being able to run forever). This is where we want to be.
Unai is in the same boat as us, but with two days less recovery time and a team which is demonstrably not as good as ours. If we come correct on Sunday, we win.
