It can, it's just Selles has chosen to play 433 but without a right winger, not selecting a more defensive mid in Soumare and then Barry is an inverted wingers, all of which means Campbell has no service and he's playing Hamer and O'Hate far too deep which has nullified both. I'd say 80% of our bad start is on Selles tactics. We're also ridiculously open and prone to the counter because likes to play everyone bar Cooper in the opposition half but we aren't pressing neither. Apart from that it's ok!
With the new additions Selles, or hopefully someone else, can play with ur without wingers, and has multiple formations we could play with this squad. Personally I'd go for 4231. I'd have liked Wilders 352 but I'm less sure that will happen with latest winger signings but Ogbene can play up top too.
