Regarding the last game between Fenerbahce and Sevilla, to be honest. Sevilla was lucky to pass the stage and beat Fenerbahce because if you check the match you can see Fenerbahce performed even better than Sevilla and they even won Sevilla with a 1-0 result which can be a reason to say Sevilla will have a problem against Manchester United if they show the same performance we saw so far from them.
With the current condition of Sevilla and seeing Manchester United it is clearly very lame.
I don't want to say that Sevilla is an easy opponent but with the current conditions, Manchester United's chance is definitely very big and I'm pretty sure about that.
Sevilla are still good enough for the Europa League especially for their defense, but it's simply not enough to face Manchester United.
