Mourinho admits he has multiple options for the No10.
"It is my favourite system," said Mourinho, as he explained his 4-2-3-1 blueprint. "Sometimes I change the triangle. Sometimes I play with one in front of the defenders and two players up and sometimes I play with double midfielders and No.10.
"This is a team where we have three or four players who like very much to be a No.10. Kevin de Bruyne likes it, Oscar likes it, Juan Mata likes it, Eden Hazard likes it. They can play in other positions but they like that No.10 position. It is a natural system for all these players to play."
