We've seen tons of chances created in the last 2/3 games alone but we just haven't scored enough. Pushing forward so much to get back in the game has cost us dear and if you look at how we played in the first 11 matches of the season, we went forward as a unit and defended as a unit. It worked well for us.
The injuries in defence have cost us dear but the fact that we CAN still create chances is good. We just need to put them away so that we stop playing catch up and altering to a more attacking formation where our defence is open to counter attacks.
I don't know if Ben Arfa will cover Raylor as well as Jonas but I'd doubt he would as he's not defensivley minded.
I think we need to give Ba some support as far as putting the ball in the net is concerned. We had Nolan from midfield last season. Cabaye and Cheik wont get that many. So we are going to need our wide men to step up.
