I assume 2 out of Quansah, Branthwaite, Guehi and Dunk will make the final squad. Dunk is almost certainly a goner, and Guehi is almost certainly on the plane.
It'll come down to Quansah and Branthwaite, and I think Branthwaite will get the nod due to him getting more minutes this season as well as his importance for his club. Quansah's star will continue rising though.
