Out of curiosity, which positions/areas do you think Arsenal should be strengthening? Lots of names are been thrown around and it is getting interesting now.
I've been arguing for a DM a la Viera for quite a bit; clearly Song was not the answer and Diaby just cannot stay healthy. Furthermore, Arteta has a couple of years left and that is about it. Maybe after today's performance Ramsey can take that rol.
Right-back is also a priority especially with Sagna's contract up in the air. Other than that I think Wenger should let the kids play: Miyachi, that Zelalem kid and Eisfeld.
A DM is clearly needed. I really wish Diaby could stay healthy, but it's too late in his career to expect that. He was playing so well at the beginning of last year too. Song was a very good midfielder, just wasn't a DM though he played good there. Arteta is getting up there, but is smart. I really liked Ramsey's performance as you mentioned, and I've always liked him because he just flat hustles every game. Maybe he could grow into the role, but I'd like to see another DM for competition sake.
Another striker/winger would be nice due to being thin there, but we have some top notch up front. I think a bigger need would be another center back just do provide coverage for Per, Kos, and TV5 (who is currently hurt). I think Jenkinson could be a good RB, but we'll have to see. I am not necessarily a fan of getting a GK. I like Szczesny and when he just reacts and doesn't overthink he is excellent.
I would love to see some of the young guys step up as you mentioned. Hopefully some can be sprinkled in for the return game next week and in a few early round domestic cup games to get their feet wet.
