As I mentioned here with some other occasions, this Brazil it seems to me weaker even than Brazil form Copa del Mondo Italia 90. They are reliant on Neymar and are having a very weak midfield. Their defensive play is really a joke if a team knows to play them on counters.
Colombia instead showed in every match they can come out and play, they showed they can be clinical and they have shown rarely are conceding. In plus they have some 3-4 genius players like James, Zuniga, Cuadrado and Jackson. Not to forget about Guarin and Yepes. This team is one of the best that is playing here.
Colombia has not lost with Brazil yet in last 4 matches, all matches being draws. Last win of Brazil is dated in 2003. IS also true that Colombia has never won with Brazil in last 12 matches, since 1959.
My bet here is about a team that has been the best side in attack if we look at their chances and their goals, but also the best side in defensive, rarely conceding. In plus they have this attitude since the qualifications as Colombia was the team has conceded just 13 goals in 16 qualification matches, the best South American side.
Expect Colombia to eliminate this Brazil.
