If the club really wanted to keep him, they'd have made a decision by now I think. I wonder if it's just a matter of waiting for us to bring in another left back. Assuming it is us being non committal (although it could be Brady too I suppose), I guess Brady might not feel particularly flattered by all the delays, and might decide he'd rather go elsewhere with a greater chance of regular game time.
Having said that, due to his injury problems last season and at Burnley, I personally think we should look elsewhere.
Lots of mights and I thinks in there, so my statements don't look too bold
