as myself and a few other sensible posters had been pointing out when he was off form, defenders dont defend is isolation and as such he suffer because the team was suffering from having a poor defensive shape, and no other defender in the world would have done much better than him under those circumstances.
now that we have regain so defensive shape, his form as clearly returned, that being said he is not quite at the PiquenBauer levels yet. PiquenBauer puts all other defenders to shame with the ease and sexiness in which he defended. the sexiness defender since marquez formed tank(oh the days of pique and marquez, awesomesss mixed with a few brain farts, i loved it). right now he still puts more effort in his defending to resolve a situatuion than he did those days, but he is excellent right now. no denying that.
