Assuming all fit
Gunn, Kelly, Clark
Patterson, Hickey, Porteous, Hendry, Hanley, McKenna, Cooper, Tierney, Robertson
McGregor, Gilmour, McLean, McTominay, McGinn, Armstrong, Ferguson, Christie
Dykes, Adams, Doak
Possibly Jack instead of McLean or Cooper - but someone is bound to miss out through injury anyway
Shankland, Stewart & Conway possibilities instead of Doak or injury to the other 2 strikers
Edit - if Barnes wants to switch when he’s fit then he’d be on the plane instead of Doak
