we need to accept, that grygera is a full back that is better going forward then defending ...
yes, he does deliver crappy crosses from the half line, but when he goes forward especially near the box he has a pretty good shot on him and adds to the offence, when you use him properly...
it is like with the other full backs (or better wing backs) like bosingwa, just on a lower level ... if you expose bosingwa with pressure, we will make his fair amount of mistakes, just like grygera ...
our problem is, that the games we attacked grygera did look good (remember the game he scored that screamer ?)
but if we let our opponents press us than grygera gets exposed and looks crap ... so it's not like he is a totally crap player, but the system we play or better the attitude of letting the game be controlled by the opponent just does not fit him.
