The America coach feels his side is the superior one heading into the Liga MX final, "but you have to show it on the pitch."
"For me, America is better, but you have to show it on the pitch," said Herrera at a press conference Tuesday. "Leon won't hide anything, it is a team that attacks the opposition but also gives opportunities at the back."
Herrera revealed that defender Juan Carlos Valenzuela is unlikely to recover from an ankle injury in time for the first leg and that he is set to name the same team that negotiated its way past Toluca in the second leg of the semifinal Sunday.
The incoming Mexico boss said getting the ball off Leon will be key to the game and that his side is highly motivated to complete back-to-back titles and finish of a near-perfect 2013 with another trophy.
"We are going to go out with everything, this team doesn't lower its guard," said Herrera, whose team finished the regular season in first place. "We have two games to put the rubber stamp on what we've been able to achieve in the past six months."
