It is fair to say that this has been the trickiest team selection Régis Le Bris has faced so far this season.
Sunderland travel to an in-form Millwall side with a lengthy list of absentees due to both injury and suspension. Whichever way he goes, he will have to field new partnerships in key areas of the pitch, and hand starts to players with limited minutes of late. Here’s how we think he might go...

18. Sub - Jenson Seelt

19. Sub - Harrison Jones
Made his Championship debut in the latter stages of the win over Sheffield Wednesday after impressing Le Bris in training of late.

20. Sub - Tommy Watson
Watson has been back in full training for over a week now and should return to the squad on Saturday. Expected to be used as an impact sub initially - replacing Romaine Mundle in games as he builds his match fitness. | Frank Reid
