Wilshere yes - both of them are far too undiscplined to work together effectievly - see Gerrard and Lampard, but he's been pretty decent alongside Arteta (see his beast mode form period of 13/14).
An Arteta/Ramsey parternership would have been perfect for the game against Newcastle where we struggled to get a foothold as he compliments Ramsey well, especially when it comes to the former's distrubution. In fact, until Coquelin comes back, I suspect we'll probably see a Ramsey/Arteta midfield against the mid to lower teams at home.
Considering we've rebuffed attempts from Real & Bayern recently for Koscienly there's no way we would willingily sell Ramsey.
Not sure if you've noticed but when the new financial deals came into effect, in addition to adding world class players to our squad we've also prevented our best players from leaving every summer.
Only way we'd sell is if he kicked that much of a stink and fuss about it, which he wouldn't. He's not that type of guy.
His distrubution is poor relative to Santi yes, but bear in mind alongside the likes of Busquets, Thiago and Alonso, he's probably the best in the world at it.
Ramsey offers us things that Santi can't - namely industry and goal threat. It'd be foolish to try and shape Ramsey into a Santi clone to try and make him the perfect midfielder in the world, and in the process lose or curtail some of the great things in Ramsey's game. Moreover we need to compliment him with someone who can compensate for some of his defeciences - I'm guessing that's where Elneny comes in.
Not that I've watched any Seria A but from the reports I've heard, Kondogbia has been a bit underwhelming for Inter considering the price they paid. Might have been a good miss.
