I like Bill's suggestion about possibly flooding the midfield as this is their only strong area IMO.
Having both Kamara and Davis sitting will give our full backs their usual license to fill the wide areas with a suggestion to play Kent and Morelos up front playing more centrally.
I do have concerns about our central defender Simpson, hopefully it will be the making of him.
Being an ex goalie i'm piss poor at the tactical side of the game but i'd go with;
McGregor
Tav Goldson Simpson Barisic
Aribo Davis Kamara Wright
Morelos Kent
