Yep I'm sure it can't be worse than Victor Moses' contribution.I don't think anyone will be particularly bothered about his defensive contribution if he gives us the drive down the right hand side we desperately need, having someone capable of bombing forward and picking out an intelligent pass or cross will free up Kulu to drift inside and offer a good passing option. I actually think our attacking coherency is going to massively improve, our players currently don't really adjust their positioning when Royal is coming forward because they're (quite rightly) expecting a horror show of a pass or cross.
Wingbacks in Conte's system are primarily attackers and should provide creativity. We have been woefully short in that department.
The 3 CBs and 2 CMs provide enough defensive cover.
