Looks like Kent is in the match day squad so could be back in contention for a place.
The 3 of them are good players, but I think we are too negative when Davis, Kamara and Lundstram play in midfield together, if they played together we would dominate possession but not create many chances. I think we should only play one of them at the same time against weaker EPL teams and two of them at the same time against stronger EPL teams.
Against a weaker team like Aberdeen I'd go for an attacking formation:
___________McGregor
Patterson Goldson Balogun Barisic
________Lundstram Aribo
_____________Hagi
________Roofe Morelos Kent
