Christian Giovanni Castillo Martínez (born August 25, 1984, in San Salvador) is a Salvadoran footballer.
Castillo's speed, ball control and exciting dribbling skills quickly made him somewhat of a fan favourite, but his first season with his new club saw him play most games off the bench.
The following season things got worse for Castillo when he suffered an injury that led to him only being able to play one game the entire tournament.
[1] On 3 December 2009, it was announced that Club León had permanently signed Castillo along with the other two Salvadorans with a three-year contract.
He made a total of 10 league games with the club, and scored one goal in a U.S. Open Cup match against FC Dallas.
After bittersweet negotiations with Lisandro Pohl, Alianza F.C.owner, he rescinded his contract calling a clause that allowed him to transfer to Suphanburi F.C.
In September 2014, thanks to the Iraqi Premier League not being recognised by FIFA, Castillo and his fellow banned Salvadoran teammate José Henríquez joined Zeravani SC.
In August, Castillo was one of 22 players suspended by El Salvador's football federation pending an investigation into match-fixing.
