Mathers is a very poor signing, and probably on a relatively big wage too.
He goes missing in physical games, which there will be plenty of in the Champs, he's not really a line-breaker, doesn't have much of a kicking game.
Solid ish full back but im willing to bet there are better full backs already playing in the Champs.
We'll be his 7th club which says everything about him, can do a solid job for a time but really not up to much.
