Real Madrid's new president Fernando Martin issued a stern warning to his players on Thursday that those not committed to the cause would not be welcome at the club.

"I don't want a team of millionaires. I want a team of marvellous sportsmen who work 24 hours a day to achieve the best for our fans," Martin told a news conference.

"Those players who think they can stay here giving only the minimum amount of effort are wrong. Those who fight and sweat for the shirt know they will have mine and the club's full support.

"I am not afraid to take tough decisions if people don't give their all for Real Madrid."

Martin's predecessor Florentino Perez, a close ally, resigned after six years at the helm on Monday, saying one of the reasons for his disillusionment was the lack of commitment shown by some players. "I will set up an independent commission to evaluate the effort of each of the players, and their sporting and personal conduct," Martin added.
