As much as I don't rate Barlaser, I dont think we'll sell him.
There's a good chance that none of our other 3 CMs will be here next season. O'Briens wages will surely be too expensive for us to sign him.
Howson out of contract and there's arguments to be made for and against giving him another year.
There's PL interest for Hackney and we will struggle to hold onto him.
We need to keep a certain amount of consistency through the squad so I think we are probably stuck with him for another season but hopefully behind 3 competent CMs. I do hope we keep at least one of Hackney / Howson. If Hackney is going to be away, we should definitely re-sign Howson.
