i see the talent, but he still doesn't inspire total confidence. when the ball heads his way, instead of thinking "right, kos will take care of that", a bit of doubt creeps in that maybe this is when he makes his 1 fatal cockup that cancels out the other 93 minutes of excellence.
that's why he's not yet rated by opposition supporters. of course, they think he's a donkey, which is totally off the mark as well.
