Re Ox, I wouldn't say no if the price was right. It's all about boosting squad depth for us at the moment. Even if you don't see him as a first team regular you have to ask if he would be an improvement on some of our existing squad players. You also have to ask yourself if he would improve in a Klopp managed, hungry Liverpool side.
If we're looking to bring in players in the £30m-£45m bracket for the first team, then we wont be getting more than three or four players. That might be a step up quality wise on what we've got, but overall our squad depth would remain relatively weak and continue to leave us vulnerable re injuries etc.
Arsenal got him for around £15m and he's been there for six years. His career has been blighted by injury which has hampered his development, but perhaps the worst is behind him on that front now. I don't know how long he has left on his contract but if he's in the last year he could be worth a punt, if only to shore up our squad depth.
The price is basically the main issue. For that money, we could probably get a guaranteed starter. BUT as a player in itself, he makes perfect sense. Pacey, skillful and can play left, right or centre midfield. We'll 100% need squad depth for European football next season. Oxlade-Chamberlain is the right kind of squad depth you want. He's not kind of guy you want in a two in midfield, but in rotation with Lallana and Gini? Seems perfectly good to me, particularly as he seems one of the few Arsenal capable of getting about the pitch.
Personally, i think he's been poorly managed by Wenger and not backed by Wenger as a young player. I don't remember him getting a real run of starts in one position, even though in this second half of the season, he's been one of Arsenal's bright sparks.
Looking at what Klopp has done with Gini and Lallana would make me get behind this signing as it seems to be a position that Klopp knows what he wants and knows exactly how to get it across to his players.
