1. Aaron Ramsey-
It is quite clear that the Spaniard does not want to retain the services of the Welshman anymore and will be looking to utilize him, as much as possible. With the injury to Welbeck, Ramsey’s role might increase a bit. However the point is, if they do not wish to extend his stay, it is best that they sell him in January, after signing a suitable replacement.
A lot of top stars want to join the north London side and they could sign a couple if needed. Offloading Ramsey would help them generate a lot of funds to sign at least a couple of players and it will be better to sell him, which could result in a bidding way, rather than letting him go for free.
One thing to remember here is that, all these players should be sold only when Emery and Arsenal are able to sign suitable replacements first and with the ambition of winning the league title and the Europa League possibly.
