Bit harsh on Patterson and mykolenko. Keane was solid at Burnley in the PL when they played to his strengths. He was good a year ago, when ancelotti played defensively to his strengths. Delph is past it now but won titles in the PL. Gomes was a decent PL standard player prior to injuries.
Holgate and Davies would get into most squads in bottom half of PL, but probably not first 11s. Iwobi would likely get into a few teams first 11s.
Gbamin, rondon and tosun have done nothing to show they are PL standard at this point. Rondon used to be.
But the squad finished 10th last season, so is clearly capable.
