Mourinho pens six-page United job application

London - Jose Mourinho has written a six-page letter to Manchester United outlining his credentials to succeed under-fire Louis van Gaal as manager, media reports suggested.

The Independent on Sunday claimed 52-year-old Mourinho, out of work since parting ways with Chelsea in December, outlines in detail his blueprint to resuscitate the Old Trafford giants who slumped to a 1-0 loss to Southampton on Saturday.

The timing of Mourinho's reported contact with United is interesting as frustrated Old Trafford fans booed their team off the pitch in the aftermath of their latest setback.

According to the report, the Portuguese coach used the letter to pledge his commitment to adapting his style of management and how he would overhaul the squad.

Mourinho has been linked with the United job before when Alex Ferguson left to be replaced by David Moyes in 2013.

As well as two spells at Chelsea, Mourinho has also coached Porto, Inter Milan and Real Madrid.
