Kelly’s return to the squad, in place of Jairo Riedewald, comes after a late fitness test yesterday. However, Vicente Guaita remains out so Wayne Hennessey remains between the sticks.
Today’s opponents have handed a Premier League debut to Kieran Tierney, with Sead Kolasinac dropping to the bench. Lacazette has overcome a recent injury to keep his starting place from Thursday night in the Europa League.
