The CSK skipper said his team did the small things right as they crushed Kings XI Punjab by 10 wickets to return to winning ways.
Fleming also rued the missing of some key players that he said has affected the team combination.
The IPL kicks off today with a repeat of last year's final, which the Mumbai Indians won by one run against the Chennai outfit.
Dhoni leads the highly-successful IPL franchise Chennai Super Kings, for whom Watson plays, with Fleming being the head coach.
Even in the previous games of this season, CSK were not able to make optimum use of the powerplay overs.
Fleming felt loss of wickets at regular intervals and failure to put together partnerships led to the team's downfall against Mumbai Indians at Chepauk.
