I wanted Naby Keita to start but since he has issues here's my line-up... and I'm serious... and yes, I don't care about winning this Cup:
Adrian
Whoever, Gomez, Matip, Milner
Gini, Lallana,
Ox
Shaqiri, Origi, Mane
This would help these guys get in shape or stay in shape, while the big guns get some rest for the real thing on the weekend.
