If the same players keep losing (regardless of formation) surely we have to make some changes. I know it won't happen, but how about:
Start: Pickford - Patterson, Keane, Godfrey, Myko - Allan, VdB, - Gordon, Alli, El Ghazi - DCL (if fit, or Rondon).
Bench: Begovic, Coleman, Branthwaite, Doucs, Iwobi, Richy, Gray.
Hard to bench Richy, but he hasn't scored when starting for a while, seems to do ok off the bench with something to prove. Doucs brings energy but not suited to a Lampard set-up as loses possession far too often. Gray not fit and again could have an impact off the bench. Whether El Ghazi should even been a Blue or not is questionable, but he does have a goal in him and brings some extra height.
Weird to think that would leave Holgate, Kenny (suspended), Mina (injured), Gomes, Delph (injured), Davies (injured), Tosun, possibly Rondon (depending on DCL) and a few promising youngsters like Dobbin not in the squad. It is clear we lack quality rather than quantity and oddly I think some of those would probably get a starting position for some of the teams around us - especially Burnley.
Whatever Frank goes for, he needs to do something different, as can't keep picking the same players who have suffered four straight defeats with no goals scored.
