The on loan striker affirmed that he has heard reports linking him to the Raposa, but is committed to rediscovering his goalscoring touch in Spain.
The Paraguayan striker, on loan in Seville from Manchester City until June 2012, has been strongly linked with a move to Belo Horizonte. The Serie A outfit is reportedly considering an exchange with City, sending young striker Leo Bonatini to Manchester in order to complete the signing of Santa Cruz.
Speaking on Thursday morning, however, the former Blackburn star affirmed that he had a job to do with Betis and vowed to improve after a poor start to the season.
"I have made a commitment to Betis. I have a challenge here and everything else is irrelevant," the forward explained in declarations published by Globoesporte. "I have heard something about the interest from Cruzeiro, but I am happy and I want to continue in Betis. That is the only thing on my mind."
Santa Cruz has found the net just three times in the 2011-12 campaign.
