4) Adam Lallana & Jordan Henderson
Summer signing Lallana has struggled to hold down a first-team place so far this season, due in no small part to the wealth of attacking talent already in the Liverpool squad. Philippe Coutinho, Raheem Sterling, Lazar Markovic, and Jordon Ibe are all competition for an attacking midfield role, so why not try dropping Lallana deeper where he can influence the game with his passing and vision. It would be an interesting experiment.
