Liga MX Week 13 Preview: Boy's debut and Leon host Pumas

After a successful international break in Mexican soccer, the Liga MX returns this weekend. Take a look at some of the Apertura's most promising storylines heading into week 13.

Club America take on a struggling Xolos

When Xolos de Tijuana turned to Ruben Omar Romano during the offseason, the hope was that the Argentine manager would focus on getting the border team back on track and into the Liguilla. After 12 games played, Xolos are 15th and without a win in their last four games.

In front of Ruben Omar Romano's side is former Tijuana midfielder Javier Guemez and Club America. The core of Las Aguilas is just returning from the international break, but Ignacio Ambriz's team will look to take advantage of Tijuana's bad form and solidify their position on the league table.

Tomas Boy makes his Cruz Azul debut

Sergio Bueno was given the axe at Cruz Azul after weeks of poor showings with the Cementeros. Now Tomas Boy is taking over a Cruz Azul side that has gone nearly 19 years without a league title. Cruz Azul hopes Boy is able to sharpen the team's attack after the club spent millions on new players.

Also tasked to turn things around is former Honduras manager Luis Fernando Suarez, who takes over Carlos Bustos' spot at relegation favorites Dorados. Both teams will meet on Saturday with the aspiration of clawing themselves back into a favorable position in the league.

Leon host Pumas in the most intriguing match of the week

With a field packed full of the season's best players, Leon and Pumas UNAM will face off at the Estadio Nou Camp on Saturday night for a spot at first place in the league table. The Mexico City outfit is ready to compete after only losing once in their last nine league games.

But Juan Antonio Pizzi's side have a perfect record at home. After taking a 4-0 beating at Monterrey, Leon will want to show the rest of the Liga MX they are championship contenders.

New national team manager, new players?

The international break saw the arrival of Juan Carlos Osorio to the Mexico national team. Facing El Salvador and Honduras next month, Osorio is officially on the clock. Univision journalist Rodolfo Landeros reported on Wednesday that Osorio will be in attendance at three Liga MX games: Veracruz vs. Santos, Leon vs. Pumas, and Toluca vs. Queretaro.

Though we will most likely see familiar faces involved in November, the entrance of a new national team manager opens the door for new players. Many will be looking to capture the attention of the new boss with the hope of one day soon suiting up for El Tri.
