Colombia are a good team but Brazil will win tonight, Neymar is an amazing player who can destroy anybody but don't forget about Firmino & Coutinho, two very talented players who will be stars of the game in the next few years, tryst me. Brazil will win this match by 1 or 2 goals.
I think it'll be close. Brazil haven't been playing their best, but I think they will take it 2-1. Could see a 1-1 draw though. Antyone got any thoughts on the Peru v Venezuela game? Think that could be a draw too.
Sorry mate I don't know enough about Peru or Venezuela be confident enough on giving you a prediction.
Just looked for you - Venezuela have a current FIFA World Ranking of 72 & Peru are ranked 61 by FIFA so judging by that there isn't much to split them. I won't be betting on that game

Here are the FIFA World Rankings if anybody is interested -
