Portuguese manager Jose Mourinho has hinted he may return to the Premier League in the future, despite recently signing a new contract with Spanish champions Real Madrid that runs till 2016.

According to an earlier report by IBTimes UK, Mourinho indicated he was very happy in Spain and vowed to make Madrid an even stronger team. However, just like former Barcelona boss Pep Guardiola, who confirmed he was ready to listen to offers after earlier insisting he would take a 12 month break, the former Chelsea manager seems to have had a change of heart. Incidentally, Guardiola was widely rumoured to be the leading contender to take charge at Stamford Bridge from interim manager Roberto Di Matteo and news he is now ready to listen to offers could well spur owner Roman Abramovich on.

Meanwhile, Mourinho has indicated the differences in culture as the primary reason why he would want to move back to England from Spain.

"London was distinct for me. I had a normal life there. In England the people are not interested in your personal life, but that is different in Spain and Italy. I need to protect my family," the Guardian quoted Mourinho as saying. In addition, the two-time Champions League winning coach said the contract extension did not guarantee the job at the Santiago Bernabeu for all four years.

"I have signed until 2016, but in a club like Madrid if you lose two consecutive games they can cancel your contract. I hope to do as well as possible in these years as I am better than ever with 10 years of experience. In 2016 my daughter will be starting university and I would like to choose in which city she studies," said the former Inter Milan boss, according to the Daily Mail.

Mourinho also spoke of the traditional dominance of the Spanish league by Barcelona and Real Madrid. He said that with the exception of the Catalans, the capital club was not threatened by any other club in Spain.

"If Barcelona didn't exist, Madrid would win the league without a coach. We accumulated 100 points and Barça 91. This is something that you don't see in leagues like Italy, France and England," said Mourinho, according to a report in the Independent. However, he cautioned this was not the case in European football.

"In order to win the Champions' League it isn't necessary to be the best, you only have to look at the final. In that, Bayern had 18 corners and Chelsea only one and look what happened. The English scored with this sole corner. Once again this just showed that in a final or a cup game anything can happen. In a league competition it is different. You play 38 games and the small details count for a lot," he added.
