Lucio was nearly excruciated at Palmeiras for his piss poor performances. Patricio idem, but at Guarani, my hometown club and the club i support. We're in third division now and trust me, even now, people here wouldnt want him back, so that tells a lot! He's somewhat solid in defense but that's it, he's an average player imho.
Tuta used to be a decent goalscorer but he's lost his eye for goal, and well, considering he's poor with the ball on his feet, he bacame useless. Sandro is strong and that's it indeed. And Tcheco is very very average, he was signed to play for Santos a couple years ago, managed 15 starts, one assist and then was promptly sold to some side in the middle-east, as fans couldnt stand his sight.
Anyway, as a team Grêmio are competent, but if you take the individualities they're mediocre, so that makes them an average to good team. With the brilliant tactics Mano Menezes is used to deploy they went pretty far away but sooner or later they would show their faults, and there you go.
