Mexico kicks off the Torneo Apertura -- the opening of its two-stage season -- this weekend.
Both its 2006-07 champions -- Guadalajara and Pachuca -- are coming off play in the SuperLiga against MLS clubs, where they showed off their American talent -- Jesus Padilla for Chivas and Jose Francisco Torres for Pachuca.
MLS veteran Daniel Hernandez is back for a second stint in Mexico, this time with Puebla. A third American -- Noel Castillo -- debuted in the Santos first team in preseason.
Here's a look at each club's offseason moves and its American connections.
The Chiapas club pulled a coup in signing forward Adolfo Bautista from Chivas, which he helped win the 2006 Apertura.
The 2007 Torneo Apertura champion and SuperLiga semifinalist solidified its attack with the signing of Colombian Luis Gabriel Rey and Rafael Marquez Lugo. It sent Omar Arellano and Luis Angel Landin to Chivas and Morelia, respectively.
AMERICAN CONNECTION:Jose Francisco Torres
Puebla will need to get out of the box quickly to avoid being relegated after only one year back at the top. Among its offseason signings is Peruvian Walter Vilchez, on loan from Cruz Azul. Eight other players were picked up in the First Division's annual Draft.
AMERICAN CONNECTION:Daniel Hernandez
Esteban Solariwas signed from Cypriot club Apoel and Rubens Sambuezaarrived from River Plate, giving Pumas an all-Argentine attack with Nacho Scocco.

The Red Devils' big signing is 32-year-old Argentine Christian Eduardo Gimenez, who had a brilliant career with Lugano and Basel in Switzerland before moving to France (Marseille) and Germany (Hertha Berlin). Another major signing for Coach Jose Pekerman is Uruguay defender Vicente Sanchez, signed from Montevideo club Nacional.
