Chelsea's self-styled 'special one' has confirmed that 'before a match in my room, I open the bible and read a chapter for a couple of minutes. It always gives me something positive'.
But Mourihno isn't the only member of the football community who seeks inspiration from his religion.
Here's 6 current footballers who have deep religious convictions:
Karim Benzema, Real Madrid
Benzema was born in France and is of Algerian-Kabyle descent. He is openly a practising Muslim
Papiss Cisse, Newcastle United
Cissé is a practicing Muslim, and when celebrating a goal he often performs the Sujud. He has allegedly objected to Newcastle United's shirt-sponsorship deal with high-interest loans company Wonga due to apparently religiously-related moral reasons (Islam considers promoting usury or financial exploitation to be 'forbidden').
Javier Hernández, Manchester United
Hernández is a devout Catholic. He is even known for his ritual pre-game prayers, in which, in front of a crowd of thousands, Hernández will kneel down on the field, hold his hands at chest level, and chant a prayer.
Kaka, AC Milan
The Brazilian is feted not only for his talent, but also for his Christian beliefs and family values.
Franck Ribery, Bayern Munich
Ribery is a convert to Islam, with his wife French-Algerian wife having been raised a Muslim herself. He is said to pray 5 times a day.
Kieran Richardson, Fulham
The England international went public about his faith in December 2011, when he celebrated scoring in the Premier League at Wolverhampton Wanderers by revealing a vest declaring 'I belong to Jesus'.
