Chelsea midfielder Cesc Fabregas says he enjoyed working with Manchester United boss Jose Mourinho.
Mourinho lost his job at Chelsea in December.
Cesc told FourFourTwo: "Working with Mourinho was fantastic.
"His passion for football, his character, his ambition to always win every three days is not easy.
"The way he pushes his players to be better every day is what impresses me the most - it was a really fantastic experience."
