Morgan now has 43 wins from 68 T20I matches he led England, while Dhoni -- who retired last year -- had won 42 matches out of 72 he played as India skipper.
The 28-year-old superstar, whose fitness is a concern heading into the event as he did not bowl in the IPL, spoke about the many challenges of his life.
MS Dhoni is the toast of the cricketing world after guiding Chennai Super Kings to a fourth IPL title on Friday in Dubai.
MS Dhoni is the most successful captain in white-ball cricket with all 3 ICC titles -- 2007 T20 World Cup, 2011 World Cup, 2013 Champions Trophy -- in his cabinet.
India will open its campaign in the upcoming T20 World Cup against Pakistan on October 24 at the Dubai International Stadium.
The CSK skipper also said if any team deserved to win the IPL 2021 title it was KKR and also pointed out that the break helped the Eoin Morgan side.
Dhoni has been at the helm for Chennai Super Kings, India, Rising Pune Supergiants in the - IPL, CL T20, Asia Cup, T20 World Cup - and has won every major T20 Trophy in the world.
Watson said that 'Dhoni just knows how to continuously bring an environment together and get the best out of the players'.
Franchise hasn’t reinvented the wheel but tweaks in the batting department has allowed them to stay ahead of the game
While captain Eoin Morgan's form remains a concern for the team on fire, KKR, MS Dhoni's finish against the Delhi Capitals in Qualifier 1 has given CSK a boost ahead of the final.
CSK has three titles with five final defeats while KKR has won both their finals under the mercurial Gautam Gambhir.
The iconic former captain was brought in as mentor by the BCCI last month when it announced the squad for the mega-event, scheduled to start October 17.
While Uthappa of course deserves all the credit for doing the job, the fact that he was persisted with in first place illustrates why CSK have entered their 9th IPL final.
CSK defeated Delhi Capitals as Dhoni returned to form with a much-needed 18 off six balls.
Needing 13 off the last over, Dhoni hit a square cut, got a bit of luck going his way and then pulled DC's best bowler Tom Curran for the most celebrated T20 boundary of recent times.
