Browne let us down only last Saturday. He was awful, and admitted it himself. And it's not an isolated game.
His passing, movement, general football tactical and space awareness is very weak for a central midfielder. Compared to Ledson, Pearo, Gallagher and DJ he is miles off. But what he can do is run, and he can shoot, they're his strengths.
I think the season he got a lot of goals, his general play was still poor. The goals masked the fact that in general play he contributes little. And his performances at fullback are crap.
Of the 5 out of contract, he is lowest priority IMO.
