Qwiss I think its a mistake to keep him. I think he was an excellent signing and he's been really good for us but he's 30 and not good enough to justify keeping IMO. He had a very hot run last season and we'd be better off using that to cash in.
I mean, we can't consider cashing in on Trossard now when we've barely got a goalscorer in the squad.
Main thing is the contract shouldn't be too long or on an outrageous wage that prevents us ever flipping him. I suspect Edu's fucked off because he knew he'd never sell Jesus or one or two others, so he knew his reputation had already peaked as far as his work at Arsenal was concerned.
Let's take a pause though and acknowledge that Trossard has actually been a brilliant, even revelatory signing despite recent poor form. He's exceeded all expectations.
