Scolari knows that Mexico will present a tricky challengeA win would see Scolari's men qualify for the second round
Brazil's head coach, Luiz Felipe Scolari, has warned his players that Mexico pose a significant threat to them in their Group A fixture this evening and told them to remember last year's Confederations Cup match as proof of the fact.
The sides met in the group stages in 2013 in Fortaleza, where tonight's match will be played, with Brazil only cementing a 2-0 win with a late goal. Scolari told the gathered press: "We know it's never easy when we play Mexico."
"It's always very even. Brazil's second goal against them in the Confederations Cup wasn't scored until late in the second half. It's always very difficult."
Mexico have beaten Brazil ten times in their history, having played each other 39 times, and Scolari knows that new coach Miguel Herrera will have made changes to his side: "The players will remain with some characteristics, but their positioning will change with a new coach."
The game kicks off at 2000GMT; follow our live text commentary from an hour before kick off this evening.
