Sevilla have snapped up Uruguayan U-20 international Sebastian Cristoforo from Penarol for a reported fee of €2.25m.
"I have arrived at a big club in Sevilla," the 19-year-old told the club's official website on Monday after putting pen to paper on a five-year deal.
"This is a great opportunity for me, I am very happy and I can't wait to start," Cristoforo added.
The midfielder becomes Sevilla's tenth signing of the transfer window as they look to rebuild following the sales of Jesus Navas and Alvaro Negredo to Manchester City. And Cristoforo will step into the role vacated by another South American as Chilean international Gary Medel completed his move to Premier League newcomers Cardiff City on Sunday.
However, Sevilla President Jose Maria del Nido insisted that the club would not be accepting any bids for France prodigy Geoffrey Kondogbia and any interested parties will have to pay his €20m buyout clause to land the 20-year-old.
