The ideal option for Arsenal is, of course, to win, but a draw is more realistic. Yes, they will let Liverpool ahead, but they will leave City behind. It is much easier to try to overtake one team than two (in case of a defeat to City).
I will be happy if any team other than City takes the title, but the most logical and “fair” option is Arsenal champion, and Liverpool wins the Europa League (the only tournament that Klopp has not been able to win with Liverpool so far).
The prediction is unlikely to win at the Etihad, but back again their ideal choice of winning of course Arteta wants to win as his away.
It is not an easy matter to overtake a team above it especially now that Liverpool are still trying to stay indeed despite the draw from Man City, I feel Arsenal will remain stuck in all positions but to go to the top of the table is a bit difficult.
Winning the Europa League will not be easy I feel Liverpool will strive for it but when they meet Leverkusen we will think twice who will win.
