But if we look at the squad, Sevilla will play without Erik Lamela, this is bad because Lamela is one of Sevilla's key player. While Arsenal will play with their good players, Saka will back after next few days. Arsenal will win with small margin like one or two goal(s).
I don't see Erik Lamela as a key player and I would rather see En Neysri or Lucas Ocampos as their key player. For Arsenal, playing without one of their key players is not a problem because they have an even squad and besides, their opponents are Sevilla, so no matter how hard Sevilla is, it won't change the fact that Arsenal will get 3 points.
It's a match like this Saka would have been eyed and tightly marked by the Sevillan defense because of his rythm with G. Jesus and his meandering runs.
I don't underestimate Sevilla in anyway but this Spanish side sits almost at the bottom of their league table as compared to Arsenal on the tippy top of the English league. It would be difficult for them to contain these English team that is hungry, fast and desperate for a trophy.
