MADRID - Real Madrid have sacked coach Carlo Ancelotti after the world's richest club by income failed to win major silverware this season and, according to local media, Napoli's Rafa Benitez is the favourite to succeed him.

"The board of directors have decided this evening to relieve Carlo Ancelotti of his duties," president Florentino Perez told a news conference on Monday.

"It was a very difficult decision ... but we have not come to Real Madrid to take easy decisions but to take decisions that we believe are the best for an institution that is a reference point around the world," added the construction magnate.

"The demands are huge and we believe it is the right moment to give fresh impetus that will allow us to win more titles and reach our optimum competitive level in a new phase."

The club will announce a successor next week, Perez said, and local media say former Liverpool and Chelsea boss Benitez, who once had a stint as a Real youth team coach, is the frontrunner to replace Ancelotti.

Others to have been linked with the job are German Juergen Klopp, who has quit Borussia Dortmund, and former Real player Michel who has had spells running the B team at the Bernabeu and clubs including Getafe and Sevilla.

Italian Ancelotti, who had a three-year contract that was due to run until the end of next season, led the club to a record-extending 10th European crown and a King's Cup triumph in his first term in charge in 2013-14.
