Pato celebrates after scoring against Ecuador in the final game of the group stages.

After stumbling into the quarterfinals, Brazil will take on Paraguay in a repeat of the group stage thriller, as the two battle for a spot in the semifinals of the Copa America 2011. 

It required a 90th minute equalizer from Fred to spare Selecao the blushes, as a thirlling 2-2 draw emanated from the same fixture in the group stages a week ago.  

It has inevitably ledto high hopes of a smiliar thriller in the quarterfinals, though the reigning champions are still the favourites despite being off form. They were handed a boost when arch-rivals Argentina were knocked out of the tournament on Saturday, though an upset today isn't unlikely.

Probable Line-Ups -

Brazil - Julio Cesar; Maicon, Lucio, David Luiz, Andre Santos; Lucas Leiva, Ramires; Robinho, Ganso, Neymar; Alexandre Pato

Paraguay - Villar; Piris, Da Silva,Veron, Torres; Barreto, Ortigoza, Riveros, Estigarribia; Santa Cruz, Barrios
