Mexico manager Juan Carlos Osorio, who is known for his policy for changing personnel between games, is making only one change for Mexico's World Cup match against Korea.
He could totally change the formation, though, with Edson Alvarez entering into the starting XI for Hugo Ayala. The 20-year-old can play at right back, center back or defensive midfielder, so it remains unclear exactly how El Tri will look on the field in thier second World Cup group match.
Alvarez could play right back, pushing Carlos Salcedo into the middle next to left center back Hector Moreno with Jesus Gallardo on the left. He could play as a right center back in a back three with Gallardo and Miguel Layun playing as the wide men in a 3-4-3. Or, he could be a direct swap for Ayala, coming in at center back while Salcedo retains his place as right back.
Layun's versatility also creates a wrinkle, with the Sevilla man able to play at right back as well, which could put Alvarez in the midfield with Hector Herrera.
It's much more clear what's happening up front with central forward Javier "Chicharito" Hernandez starting as the No. 9. Hirving Lozano will be to his left after scoring in his World Cup debut with Carlos Vela either on the right as an inverted winger or behind Chicharito, as he was in the contest against Germany with Layun to the right of Vela.
Moreno and Herrera would miss the next match if they were to be booked in the match.
Korea manager Shin Taeyong has gone with two changes, bringing in midfielder Ju Sejong and Moon Seonmin after a 1-0 defeat to Sweden to open the tournament.
Mexico XI: Ochoa; Alvarez, Salcedo, Moreno, Gallardo; Layun, Herrera, Guardado; Vela, Chicharito, Lozano
Korea XI: Jo; Lee Y., Jang, Kim Y., Kim M.; Moon, Ju, Ki, Hwang; Lee J., Son H.
