After finishing the season empty-handed with Real Madrid, Mourinho announced his intention to return to Stamford Bridge and was confirmed as the new manager of Chelsea on Monday.
The Portuguese spoke openly about his desire to improve the Blues and Crespo told The Sun that he expected the side to be driven to success by Mourinho's hunger to win.
"Everybody in football wants to win but I have never seen anybody who wants to win with the same intensity of Jose. He doesn't care if he plays beautiful football, he doesn't care what the opposition say about him, he doesn't care what the media say about him. All he cares about is having trophies at the end of the season," Crespo pointed out.
"I am sure that Chelsea will now dominate English football again."
Chelsea's Premier League rivals Manchester United and Manchester City will also be led by new bosses following the retirement of Sir Alex Ferguson and the sacking of Roberto Mancini, but the former striker believed even Ferguson would have found it difficult to compete with Mourinho had the Scot chose not to step down.
"I think even if Alex Ferguson had stayed at Manchester United then Chelsea would still dominate because Jose is so special," Crespo said.
"And with Ferguson gone I do not even see any competition for Jose. He is on another level."
