Ofcourse its all Colombian! What did you expect? The Merconorte is a joke of a tournament, everybody knows that.
Let me tell you a little about the Merconorte. The CONMEBOL divided the region into 2 tournaments, The Mercosur was made for the great teams and the Merconorte was for the weak teams (all of this happened before Colombia became good) You cant compare teams from Argentina, Brazil, Uruguay, Paraguay and Chile to teams from Peru, Bolivia, Ecuador, Venezuela and Colombia. Why do you think Mexico was added? because it was the most boring cup on the face of the earth. Im not saying that Mexican teams are the best, but somebody had to give Colombia a run for their money.
Colombian teams in the Merconorte are like Mexico in the CONCACAF, they are expected to win every year.
PS - Colombian teams would not survive in the Mercosur.
Hurrah for Paquador!
