He said, “I don't see any reason why we wouldn't go to Miami and put on a real show. There's still a lot of upside in this fight.”
Earlier, Monterrey's USA striker Brandon Vazquez scored on his return to his former club Cincinnati as the Mexican club won 1-0 in their first leg on Thursday.
Cincinnati got off to a bright start and had the ball in the net in the 18th minute but Corey Baird's effort was ruled offside.
Six minutes later, however, the Liga MX team were ahead and it was former home favorite Vazquez who made the breakthrough.
Maximiliano Mesa found the forward in the box and his right-footed effort went under the body of Cincinnati keeper Roman Celentano, who should have done much better.
It was Vazquez's seventh goal in 11 games since joining the five-time CONCACAF champions and will strengthen his bid to be included in Greg Berhalter's USA squad for the upcoming Nations League Final Four.
Monterrey were reduced to ten men in the 70th minute when a VAR review found that Rodrigo Aguirre had hit Baird on the ball before a corner.
