Even though Sevilla is quite at home, I don't think Arsenal will be as disappointing this time as before when they lost against Lens. What is certain is that Arsenal needs points to maintain their probability of qualifying for the last 16 and there is no way they will lose this match. It is quite difficult to determine the outcome of betting on this match and the safest is BTTS because both teams will definitely score goals against each other. It is possible that the score will end in a narrow 1-2 win for Arsenal. There is nothing else that makes Arsenal lose this match and we can see their motivation increasing after winning over their rivals in the domestic league last week.
Sevilla also same, they also need points to overtake Arsenal and qualify for the next round, so it's not a thing should be discussed.
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).
