Then you change your approach and bring in players to actually improve the team rather desperately cling onto players who clearly don't give a fuck about playing for you? While both are good players it is not like we are talking about Messi/C.Ronaldo type players who you fight to keep at all costs.
Both are frustrating as fuck despite their goals/assists this season. If we finish in the Europa club and with Wenger what makes you think either of those two will want to stay? Then you get stuck with two players who will kick up a right stink in the summer and further act like a bunch of stroppy fucks all of next season and then lose them for free. So what do you suggest then?
There will be players available, of course if you don't offer them big wages they won't join. So when you fuck up like us then you need to cough it up.
