Tired Southampton on Tuesday
All Premier League matches are of paramount importance to Arsenal until the end of the season, and heading back to a stadium that has not been a happy hunting ground in recent years on Tuesday, Southampton are now there for the taking.
Hasenhuttl fielded a side as strong as he could have on Saturday, with all bar the goalkeeper expected to take to the pitch once more on Tuesday. Arsenal, by contrast, have Kieran Tierney and Smith Rowe to come back in without playing a single minute, Partey’s help with build-up phases from the start, Alexandre Lacazette to add bite in attack and Saka to keep the Saints’ defence occupied.
Pierre-Emerick Aubameyang is an uncertainty.
That freshness puts Arteta’s side in good stead to claim three points against a side who’ve won just one of their last six Premier League encounters.
Nothing is a given as far as Arsenal are concerned. If you’re in search of reassurance though, that comes as a bonus, regardless of how meagre it may be.
Even with fatigue, Southampton can play better than they did. They didn’t need to be at their best to win on Saturday. Yet with upgrades in positions across the pitch for Arsenal in round two, they will show more fight and will play better. They have to.
