The 61-year-old Italian, who has coached AC Milan and Juventus in Serie A, still has two years left on his Real contract, but his future is far from assured given his fractious relationship with the club's president, Ramon Calderon.

Capello told Onda Cero radio Tuesday that "I have the feeling they will seek out a new architect for the new project."

Asked what he would do if Real show him the door, Capello told Italy's Gazzetta dello Sport: "I've already coached the best teams, so I could quit two years early."

He put his chances of staying with Real, whom he also helped win the Spanish title in the 1996-97 season, at 50-50.

"It's on the toss of a coin," he said. "All I know is that I would like to stay here to win the Champions League. I have already booked my flight (back to Spain) to return on July 19, because training starts on the 20th."

It seems unimaginable that Calderon would consider replacing Capello after the Italian engineered a success that seemed unlikely three months ago, but Real have sacked successful coaches before.

German coach Jupp Heynckes was sacked just days after Real won the Champions League in 1998 and Vicente Del Bosque, mooted as a possible successor to Capello, did not have his contract renewed in the summer of 2003 despite leading Real to two Champions Leagues and two La Liga titles in four years in charge.

After the title was won Calderon would only say that the Italian was under contract but AS magazine headlined "Schuster for the 2007-2008 season," and added that "Calderon has chosen Schuster" in reference to former Real midfielder and current Getafe coach Bernd Schuster.

Sporting director Pedja Mijatovic described Capello as having a "good project" and told Marca magazine that Fabio Capello, who still has two years to go on his contract, is the perfect coach to win further titles."

Calderon insisted that it was not his role to choose the coach. "The people in charge of the sporting side must decide, and I will do what they say. It is up to Mijatovic," he said.

But "I have a magnificent relationship with Capello," he insisted on Cadena Ser radio.

Three months ago Real were five points adrift of Barcelona. But an unbeaten run since then saw them grab the title and prevent a Barca hat-trick, after which Capello said he wanted to carry on but would have to talk to Calderon about the future.

Calderon meanwhile told Spanish radio that signing long-coveted Brazilian star Kaka from AC Milan was possible but unlikely and held out little hope of netting Manchester United's Cristiano Ronaldo.

"It is a remote possibility that Kaka will play for Madrid (but) it is easier for him to play in Madrid than Cristiano Ronaldo."
