Chennai Super Kings skipper M.S. Dhoni suggested his side needs a shake-up after they lost a nail-biting Indian Premier League final by one run to archrivals Mumbai Indians.
The thriller saw Mumbai edge out Chennai after Shane Watson fell short of his ground for an unlikely second run in the final over to end his belligerent innings.
Chennai then needed two off the last ball to overtake Mumbai's 149 but Lasith Malinga trapped Shardul Thakur leg-before wicket to claim a record fourth title for Mumbai.
"We need to go back and reflect as to how we reached the finals. I don't think it was one of those years where we played really good cricket and we got into the finals," said Dhoni.
"After the World Cup, once we come back, that's the time we get to the drawing board and see what can be done to fill the gaps.
"Nothing against the bowlers, but batting could have been better," said Dhoni, whose team has won three IPL titles from eight finals.
None of Chennai's batsmen made it to the top-10 run scorers list in this year's IPL.
Dhoni, 37, was Chennai's best batsman with 416 runs, including three fifties.
Watson's return to the IPL next season was already uncertain after the 37-year-old retired from Australia's Big Bash early this year.
The Australian all-rounder and Dhoni are among the 11 members of the 25-man Chennai squad aged over 30.
Dhoni was run out in Sunday's final for two, leaving the defending champions in trouble at 82-4.
"We committed a lot of mistakes and Mumbai Indians also did the same and at the end of the day the winning team was the one that made one mistake less than the other team," said Dhoni, adding that his immediate focus is on the 50-over World Cup starting later this month in England and Wales.
The Rohit Sharma-led Mumbai were the team to beat this year in the world's most popular T20 competition, ending on top of the table after 14 league games.
"We played some good cricket. Good to see we qualified in the top two," said Sharma.
"Our bowling in this tournament was excellent. At different stages, our bowlers put their hands up and brought us back in the game."
