Who CURRENTLY has the best cantera in Mexico, Chivas or Pumas ?

Currently I say Chivas because if Pumas pass to the final it doesn't mean its because its their cantera. 1/2 the starting line-up were formed in other clubs (Palencia, Veron, Dante, Leandro, Martin Bravo)... While all the startes in Chivas were formed in Chivas (including Arellano, he played his youth in Chivas but debuted with Pachuca... also Bofo is not a titular anymore)...Also, most of our cantera players are better and more experienced than their cantera players....
