The Blues manager's first spell at Stamford Bridge was derided for his negative approach but the Portuguese promises that his team will win with style this time around.
The Portuguese's first spell at Stamford Bridge was largely successful but the Blues still came under criticism for a perceived negative approach to matches. The 50-year-old says that his aim is to make the supporters happy by the results and the style in which they are achieved this time around.
"I want to make the Chelsea fans happy - by results, by our playing style, by the mentality and the personality of the team," Mourinho told The Sun. "They have to know that we always give everything. I know from my record at Chelsea, also at Inter and Madrid, that I made many decisions that helped my teams.
"If I gamble with a very risky decision, it can go the wrong way. How many times did I play here with three defenders? I remember against West Ham [in April 2006] we were losing 1-0 and we were playing with 10 men after Maniche got a red card early in the game. I still gambled because I wanted to win with 10 men — and we did win, 4-1."
The Blues have announced the arrival of youngsters Andre Schurrle and Marco van Ginkel already this summer but the former Porto coach says that the Chelsea old guard still has a part to play.
"This is the legacy of the club culture — as some guys are arriving they have others who can transmit to them immediately what this club means," he said.
"One day, these older players will finish and the younger guys now will be the older ones in the future, so the Chelsea culture is continuously passed on from one generation to the next."
