Pachuca suffered through a less-than-stellar Apertura 2009 campaign but the club made a significant upgrade that could prevent a further fall from grace next year.
Club president Jesus Martinez told Mexican daily
"The deal has been finalized," Martinez told
Cvitanich, 25, was born in Argentina but holds a Croatian passport. He spent five years with Banfield in Argentina before moving to Ajax in 2008. He scored 13 goals for the Dutch club but had a falling out with Ajax manager Martin Jol and his playing time dropped.
Martinez said Cvitanich will join Pachuca for one year on a loan with an option for an outright purchase.
