Mourinho started looking for moles at Real Madrid from his first day in charge Real Madrid The first episode of a new series by MARCA

This is the first episode in a new series called 'MARCA: Stories We Never Told,' a collection of stories and anecdotes that, until now, were filed in our drawers for different reasons and are now seeing the light.

Jose Mourinho came to Real Madrid to bring back a winning mentality to the club and to impose discipline.

The club felt that Manuel Pellegrini, his predecessor in the job, was unable to deal with the heavyweights in the dressing room.

But Mourinho's arrival was not easy because it was a World Cup year and he began his first few training sessions with half of the squad still on holiday.

The Portuguese turned up at the Estadio Santiago Bernabeu with a whip and the reputation of being the best coach in the world, but his desire to impose his law from the first saw was felt the most by the youth players and those in the first team who were not in the starting line-up or in his plans moving forward.

The main group Mourinho wanted to build around, in the middle of July 2010, were still on holiday after playing the World Cup in South Africa, while the Spain players were the last ones to return after having lifted the trophy.

Mourinho brought the group together for their first training session at Valdebebas to make his rules clear, which were exclusively unveiled by MARCA the following day.

If the Portuguese took a hard-line approach on the first day, the second saw him take things up a notch as he began to look for moles in the dressing room.

Before leaving for training, Mourinho had a warning for his players.

"I've already seen that there are cameras in the dressing room; I'll find out where they are," he said.

After the session, the former Porto, Chelsea and Inter boss gave a press conference in which he slipped in the same message.

It was only later that it became known that Mourinho had identified some players whom he had accused of being leaks, but his obsession was already being confirmed by the players from day one.

Mourinho's anger was known when he jumped on the media regarding the line-up he had decided on before it had been publicly announced.

Among the rules of conduct, Mourinho warned his players that mobile phones should be on silent whilst on the bus, that injured players had to arrive an hour early to be examined by the doctors, and that he would not accept any player being late.

Anyone who was not on the pitch at the scheduled time for training should not go out to train at all: "I'm not waiting for anyone."

This was the start of the Mourinho era.
