Why would you leave Xhaka out? Tottenham aside, he's been one of our best and most consistent performers post break. Laca has also been very good in recent games, so he needs to start too.
I think Saka needs a break too, so I'd go with:
Emi
Mustafi - Luiz - Tierney
Bellerin - Ceballos - Xhaka - Nelson
Pepe - Laca - Auba
But I'd expect to see Tierney move back into the LW position with Holding/Kola coming in and Nelson on the bench.
2-0 Arsenal.
