Chicharito, who spent the past three years at the Major League Soccer (MLS) club LA Galaxy, signed on a free transfer after leaving the MLS outfit in November.
The striker went through Chivas' youth ranks when he started his career and played for their first team from 2006-2010 before making a switch to Europe when he signed with Manchester United.
Chicharito helped United to two Premier League titles in 2010/11 and 2012/13 and featured in their 2010/11 Champions League campaign when they finished runners-up.
He went on to play for Real Madrid, Bayer Leverkusen, West Ham United and Sevilla. He is the top scorer of the Mexican national team with 52 goals.
