Gruev is surely going to struggle to get back in this side...
Unless any of the other 3 get injured, I'm really not sure how Gruev is going to get back into this side... Not to mention the experienced presence of Guilavogui is there too.
Gruev doesn't offer anything different or better than what Ampadu, Tanaka and Rothwell do.
I'd go with Ampadu and Tanaka
