This is as complacent as it gets. Look at the teams Colombia has beaten in the last year (Spain, Germany, Uruguay, Brazil) and tell me again this will be an easy match for Argentina.
Argentina had an easy time reaching the finals due to only playing against small teams (almost lost to Ecuador anyway)
While Colombia actually played against the second best team in the tournament and won with only 10 players in the field.
Rn, it is undeniable Colombia is in better form going into the final.
