You haven't played 15 matches under Montella yet. Have you?
Anyways, it's true Muriel offers some qualities but he's too selfish for me to be an undisputable starter. WBY should get his chances more often. I'd say this is Montella, who had coached Muriel before, playing it safer.
That said, WBY has wasted too many chances this season, too.

But for me, he's a better player. This Sevilla side will create a lot and there won't be anyone able to finish it. Won't work vs. better teams.
Would even consider playing both of them at the same time, but it's also true that Sarabia does offer some things, cover for some 'dirty work'. Would be better if he stopped competing with Banega.
Really looking forward to the match. What's up with Jesus? Will he be ready to play? What lineup do you expect?
