We have needed a cb since this summer, not seasons. I can admit that we needed a holding midfielder last season due to Arteta ageing and the fact that his legs are fone. Last year, we won a trophy and advanced compared to other years. I would say that this is the first year where we are realistically underachieving. Before 2013, the money was not there, however that changed since we bought Ozil. I would be very frustrated if we finished 4th, however teams aren't built in a season. This summer, 4 first team players left as well as needing replacing. We signed five in the summer as well and bringing back Joel Campbell. It's very hard to get more than 6 in during the summer window, particularly if you look at the quality we have signed. One area in which we are underachieving, is our league form. I can see why Arsenal fans are frustrated with 4th every year, however if you consider how financially crippled Arsenal have been in the past, it's a miracle that we have been in the champions league for so long! I expect to see a proper challenge for the title and the Champions league next year. There shouls be no excuse for no defensive cover in the next 2 windows and I know that we will complete our squad by the summer.
