The Portuguese international has two years left on his current deal with Madrid and earlier took on social networking site, Twitter to deny reports he has extended contract with the La Liga giants.

The forward's recent comments have raised concern over his future at Santiago Bernabeu, which has seen him being rumoured to re-join his former employers in the summer. However, Perez remains confident that the 28-year-old will sign a contract extension before the beginning of the new season as Madrid are looking to build the future team around him.

"He's our most important asset, and we will build the future of Madrid around him. Soon we will clarify this issue. I have no doubt that Cristiano [Ronaldo] is going to retire at Real Madrid. I'm convinced that he'll renew. The renewals are done before the season starts," said Perez, as quoted in

Apart from keeping Ronaldo at the Bernabeu, Perez has also set his eyes on signing Tottenham star Gareth Bale in the summer. The PFA Players' Player and Young Player of the Award winner has been a priority transfer target for Madrid.

The Spanish side's chief believes spending big in the summer to sign Bale will help them increase their income and at the same time, Perez believes Madrid can also attract other top class players in the transfer market.

"I try to make it that the best players in the world play for Madrid. Players are never expensive or cheap. It depends on the performances that they provide. Figo, Zidane, Ronaldo and Beckham gave us a massive jump in income. If you invest if great players, you will have more income," Madrid president said.

"That allows, firstly, the club to be independent and in the hands of the members, and, secondly, to attract other great players. We want great footballers who work hard and understand this club and its history. Those that know me, know I always want the best to come to Madrid," Perez concluded.
