The only places i think we need to strengthen is definitely another striker/forward to give some more competition in the squad. I wouldnt rely on our last Samurai to be honest and of course once Walcott and Pod are back fully fit then we can use them but id still like Wenger to get a proper out and out striker ie a fox in the box type of player. But in Jan it will be difficult to get someone of that ilk as most players wont want to leave and neither would teams sell those players etc.
The other positions i think we need a little bit more depth is in our defence, ie a cb or 2 to back up Mert or Kos should they get injured. Verm as great as he has been for us in the past cant be relied on as hes far too injury prone for my liking and i think Wenger will be using him as a sub more or less now.
Midfield we are set with Rosicky, Ramsey, Wilshere, Ozil and Cazorla all able to interchange at times. It was breathtaking to see Ramsey, Ozil and Rosicky click so nicely last night, the interchange between them 3 was immense. Cant fault really anyone last night as the whole team put in a hell of a shift against Napoli. Fingers crossed we keep up this momentum as our fans definitely need it after the yrs of mediocrity that we have displayed on the pitch.
I was giving quite a bit of credit to the Napoli fans for creating a brilliant atmosphere last night even when they were losing but as per usual Italian fans show their utter stupidity as well.
