Real Madrid president Florentino Perez has set his sights on signing Cristiano Ronaldo after completing a move for Kaka.
AC Milan playmaker Kaka joined Madrid on Monday night for a fee of ¦pound;59 million and Perez is eager to continue his 'galacticos' policy of pairing the Brazilian with Manchester United winger Ronaldo.
Perez told Sky Italia: "We are always thinking about great players. Cristiano Ronaldo and Zlatan Ibrahimovic are among other great players around the world."
He added: "We all know that these are players that we would like to buy but they can't all come."
Perez's comments are likely to infuriate United, who voiced their displeasure last summer at Madrid's public pursuit of the Portugal international.
And Perez insisted any move for Ronaldo this time would be done via the right channels.
He added: "Ronaldo is a great player who we would like to bring to the club but first we have to speak to Manchester United because the important thing is for us to maintain a good rapport with everyone."
