Sounds like we could and should have won by a very long way, which is very impressive against a good footballing team in strong form.
Cav is devastating atm, but I still feel his impact is always greater off the bench.
Don't agree Costa doesn't fit this formation either. Whilst I agree he would work better as an out and out winger, I can see him coming good in this formation. The only worry this season that appears totally missing from his game is his finishing. He showed last season this wasn't a problem, so it's about finding confidence. That said Dicko's finishing always was quite good and then he was injured and in was....rather poor. For a long time. So I hope Helder does rediscover it soon as he is the weakest performer atm and we can't carry that forever.
To clarify, I still think his all-round game is good, and he is offering a threat (maybe Bristol was an off game), but if he doesn't want to be replaced in the summer, he needs to start scoring again.
