REAL Madrid have set their sights on adding Cristiano Ronaldo to their superstar squad after completing a move for Brazilian superstar Kaka.

Club president Florentino Perez told Sky Italia: “We are always thinking about great players. Cristiano Ronaldo and Zlatan Ibrahimovic are among other great players around the world.

"We all know that these are players that we would like to buy but they can't all come.”

Kaka signed from AC Milan for �59 million last night, and any move for Ronaldo - who has recently pledged his future to Manchester United - would surely cost the Spanish giants at least as much.
