Anyways you're not going to drop points against Southampton with just one player playing badly-
Holding was below average
Zinchenko made mistakes defensively
Partey was v sloppy
Jesus missed chances
Ramsdale dropped a clanger
Trossard starting and a better start we could have survived the rest of the above
I really think Arteta would've started Trossard for Saka (He couldn't drop Jesus/Martinelli due to form) but would've killed his confidence with the penalty miss and being dropped
