Attack – Pepe, Lacazette, Aubameyang
Smith Rowe is not the only player who could be rested by Arteta.
Bukayo Saka has played a lot of football of late and could be held back ahead of Sunday’s match against Manchester City and the return leg next Thursday, with Nicolas Pepe starting instead.
Alexandre Lacazette did not feature against Leeds so is likely to come into the side.
And captain Pierre-Emerick Aubameyang will aim to build on Sunday’s confidence-boosting hat-trick.
Expected Arsenal XI vs Benfica in full: Leno; Bellerin, Holding, Luiz, Cedric; Elneny, Xhaka, Odegaard; Pepe, Lacazette, Aubameyang.
