Jose Mourinho insists he hasn't signed a pre-contract with Manchester United.

A report in March indicated Mourinho signed a pre-contract with United in which he would be paid £15 million if he wasn't named manager of the club.

"[Van Gaal] is my friend, I worked with him for a few years," the Portuguese coach told Sky Sports. 

"I am always linked with jobs and in the summer I will have a job, but in this moment I can promise you I do not have a contract with any club.

"I am not in a position to turn [jobs] down, I am in a position to analyze. I am in a position to be open to any club or national team."

Mourinho would prefer to remain in the Premier League.

"I have to be honest, if possible I would prefer a club but I must analyse to see what is best for my career and to be back with everything I have," the 53-year-old said.

"I would prefer [to be in England]. I love the country, I love the football here, my family is very stable and happy.

"If possible, yes, it would be my first choice."
