The Mirror says Sheikh Mohammed Bin Rashid Al Maktoum, one of the world's richest men, has made contact with the Portuguese's agent Jorge Mendes to make the stunning offer.

Mourinho was on £5.5m-a-year at Chelsea and would seem highly unlikely to take the job - but the size of the offer may make him think him twice.

Sheikh Mohammed failed with an attempt to take over Liverpool and is a deeply passionate football fan.
