Blackburn sign Santa Cruz's brother
Julio Sana Cruz agreed a three-year contract with the Premier League team, subject to international clearance.
The 18-year-old forward, who played for Cerro Porteno in Paraguay, had been on trial since the end of last season.
Now he could play alongside Roque in Blackburn's attack if his brother decides to snub interest from Manchester City and stay at Ewood Park.
"I am very happy to be here at Blackburn, it will be an amazing adventure for me," Santa Cruz told the club's website.
