How much of a difference is there between playing the wide players as high up as possible in the STR/L positions rather than the AMR/L positions? I'm struggling to find a tactic using wingers that is attacking enough. I've been playing as Crystal Palace and it seems to be a case of either being defensively vulnerable or offensively useless. With Zaha and Bolasie (although I'm not sure how good he is on here) creating chances should not be a problem but I've found it hard to find a tactic that works and I thought moving the wingers up could help.

Any thoughts?
