A ticket to the final is on the line with the Red Devils trailing the series but in front of a supportive crowd at the Estadio Nemesio Diez
Club Tijuana dominated the first leg of its semi-final series with Toluca but allowed a late goal that has the series in play after a 2-1 Xolos win in the first leg.
The series will be decided Sunday afternoon at Toluca's Bombonera, where the Red Devils haven't lost in 2018.
Tijuana won't be too intimidated by a strong home record, though, after beating Monterrey at home in the quarter-final.
