Seems to me as though our first priority is to offload the high earners and free up the wage budget, cover that with loan signings until the end of the season and then with our new found freedom in the wage budget we go into the market for our main targets/more long term solutions in the summer window.
If you think about it; assuming we did sale Özil in addition to Ramsey leaving, Welbeck's contract expiring, Ospina potentially sold, Cech retiring, Elneny sold suddenly our wage bill is going to be dramatically reduced and based on this season none of the above are guaranteed starters for us.
Can see us doing some good business in the summer window once all of the above have been dealt with in one way or another.
Hopefully i'm not being too optimistic.
Koscielny too, maybe Monreal and Mkhi, there’s scope to take a lot of money off the wage bill. You could also try selling Mustafi, Chambers, Kolasinac, Xhaka...just empty the place basically.
