Our squad is looking pretty stacked atm. Obviously if Vermaelen leaves and we don't replace him with another experienced CB then our defence would actually be weaker so I think it's imperative we keep hold of him, and especially we shouldn't be selling him to United and helping their rebuilding process. DMF is still an area of weakness, Arteta is competent against the weaker sides but we need someone like Carvalho/Schneiderlin to come in and provide a physical presence and shield the back four. Look at our tital rivals, City have Yaya/Fernando/Fernandinho, Chelsea have Matic, Liverpool have Can who can become a midfield powerhouse. The closest we have is Diaby and if stays fit then we're sorted in that position but that's a big gamble so we definitely need to bring someone in.
Disappointed we didn't go in for Mandzukic too. He may not be the striker that is a massive improvement on Giroud but he's someone that would allow both of them to flourish as Giroud suffered burnout last season, plus he's also a big game player which Giroud is not. Sanchez/Walcott/Podolski should not be considered strikers, they are all wide forwards and there is difference that Wenger does not seem to grasp. Should have been in for Griezzmann too, if you think about it if Sanchez replaces Theo and Griezzmann starts over Cazorla we become much more dynamic up front, Sociedad payed us around £12m for Vela so we could have given them £10m + Vela which wouldn't have been a bad deal at all, obviously one of Cazorla or Poldi would have to be sold for that to happen and I think Wenger wants to keep both, which personally is the wrong decision. I think those two players we missed out on tbh.
