Wasn't sure at first but I trust MW 100% and if he wants him then that's good enough for me and for all the things you can say about Joey Barton, you can't say he's not a talented footballer and will enhance the team.
For those saying his age is an issue I would ask you to think about how much MW wanted Eustace in the team at 36 years old for his experience as well as his ability then I would say that Barton is above Eustace in all aspects.
Even if we don't get Barton I still think we are on the brink of something special.
