Guillermo Alvarez, Cruz Azul's president, told ESPN Deportes that the deal to sign Barrera "will be defined [on Friday]. It's about 70 percent done." Alvarez noted that the negotiation still hinges on West Ham's approval.
Cruz Azul has already signed Argentine striker Mariano Pavone as well as former Atletico Madrid defender Luis Perea to beef up its lineup prior to the Apertura 2012 season.
Barrera, 25, left Mexico for West Ham in 2010 after a stellar World Cup in which he memorably bewildered the French defense in El Tri's 2-0 victory.
With the Hammers, Barrera appeared in 15 league games, starting six. In 2011, he was loaned out to Zaragoza following West Ham's relegation. In Spain, Barrera scored his first European league goal but was largely pushed to the bench following Mexican manager Javier Aguirre's dismissal.
Despite tough times on the club front, Barrera has had unwavering support from Mexico national team boss Jose Manuel de la Torre.
In the 2011 Gold Cup, Barrera scored three times en route to Mexico's sixth title, including a brace against the United States in the tournament final.
