Chennai have been dubbed "Dad's Army" by the media because of their use of over-35 players including Dhoni, Watson and Du Plessis
Three-time Indian Premier League champion Chennai Super Kings will be forced into major changes after a humiliating defeat to arch-rival Mumbai Indians, their veteran captain Mahendra Singh Dhoni said.
Dhoni's team suffered a crushing 10-wicket loss in Friday's clash that is widely considered Indian cricket's El Clasico drawing a huge TV audience.
Mumbai and Chennai, both huge spenders on international stars, are now at opposite ends of the eight team table.
Mumbai are strong candidates for a fifth title while Dhoni's side are virtually certain to miss the playoffs.
And he admitted after an eighth defeat in 11 games that this "hurt".
Chennai could manage only 114 for nine, a total four-time champion Mumbai chased down in 12.2 overs without losing a wicket.
Chennai have been dubbed "Dad's Army" by the media because of their use of over-35 players including Dhoni, Shane Watson and Faf du Plessis.
That will now change.
Dhoni, 39, who retired from international cricket in August, said young players will be blooded for the remaining three games.
Watson was dropped for the Mumbai game but South African Imran Tahir, 41, played his first match of the season.
Dhoni, once of the game's best finishers but who took more than a year off after India's elimination from the World Cup, has been slammed for his go-slow approach this season.
Chennai "are looking like an ageing boxer in the ring against younger fighters who are throwing more punches than he can handle," veteran commentator Harsha Bhogle wrote on Twitter.
Former India captain Kris Srikkanth wrote in The Times of India newspaper, calling for the legendary wicketkeeper-batsman to go back to his traditional "fearless and attacking" tactics.
