Rovers swoop for duo
Blackburn have signed Barcelona striker Ruben Rochina for an undisclosed fee.
The 19-year-old has signed a contract to keep him at Ewood Park until the summer of 2015.
Rovers have also signed Argentinian midfielder Mauro Formica on a three-and-a-half-year deal.
Blackburn boss Steve Kean told www.rovers.co.uk: "Ruben is a genuine addition to our senior squad, a young player with great ability who can play in a number of attacking positions."
"He joins our elite development group alongside the likes of Phil Jones and Junior Hoilett and will compete for a place in the team from the word go.
"The fact we are able to sign young players from the likes of Barcelona is further evidence of the owners' intention to push the club forward.
"They told me they were keen to add to our youth development group and this is a significant and exciting signing for us."
On 22-year-old Formica, signed from Newell's Old Boys, Kean added: "Mauro is a fantastic talent, an attacking player who has been in great demand," Kean told Rovers' official website.
"He has great technical ability and is a typical Argentinian with a bit of fight and a bit of devilment in him."
The duo follow Jermaine Jones and Roque Santa Cruz into Ewood park this transfer window.
