I'll bite.
Although I will say that he has his hands tied at times, I find the timeliness and selection of some substitutions questionable, especially when it comes to Stambouli. We have given up a lot of late goals and he has the ability to come into a game, break up an attack and has the pace and energy we need to quickly get active into a game. Coming on in the 85th minute doesn't give him anywhere enough time to make an impact.
I'm still not sure, at the moment, why Fazio seems to have lost his place to Dier and think that it has been partially to blame for our recent inability to keep a clean sheet and has allowed teams the ability to be more effective with aerial balls into the box.
Although I think he was just experimenting and, dare I suggest, rotating a little, Eriksen is not a strong player for us on the left unless his function is to pull back into the middle, and Dembele is not a CAM.
