My point being that I don't think we can play 4 attacking players from Mane, Tadic, Long, Pelle, J-rod, Juanmi without it effecting the balance of the team. Things certainly improved when Romeu came on and I think him and Vic will form a great partnership, however I still feel we need someone who can link the midfield and attack whether that be Davis/JWP or Clasie when he's fit.
We tried 'four' on occasions last season, even with Morgan around, and I still didn't feel it worked that well. I'd much rather see 3-5-2 with Cedric and Targett / Bertrand as marauding wing-backs *****il such a time as Cedric knows how to defend).
All IMO of course.
