Calafiori and Timber return to the Arsenal defence
GK – David Raya – Raya returns to the starting XI this week after Kepa Arrizabalaga started against the Saints.
LB – Riccardo Calafiori – The Italian international came off the bench against Southampton, but he should be in line to start this week.
CB – Gabriel – Gabriel did start over the weekend, but he is also expected to make a start this week in the huge Champions League clash.
CB – William Saliba – The Frenchman is fit and ready to go, so Arsenal should have their strongest defence against Sporting.
RB – Jurrien Timber – Timber was injured during the international break, but he should be back this week.
