He also played behind Merts, Johan D who we know is terrible TV 5 who by his standard has not had the best season and Santos and Gibbs who have both not had the best seasons.
I don't see how defending Ches means Kos is shit he is far from it. i might mean some defenders have not been up to scratch this season.
Merts has been woeful at times lets not forget that.
Only reason we have conceeded more with Ches has nothingto do with how bad a keeper is and more to do with how shite we are defenisively this season as a team.
