Chasing a target of 171 runs in a rain-curtailed game, Chennai got over the finish line in the last ball.
Ravindra Jadeja emerged as CSK's saviour, scoring 10 runs in the last two deliveries.
After being asked to bat first, Gujarat Titans scored 214/4.
Sai Sudharsan was the Titans' leading run-scorer, accumulating 96 runs in 47 deliveries.
CSK Vs GT Live: Another Season of MS Dhoni (Hopefully)!
We have an answer from the man himself! Well, somewhat of an answer, at least.
"This is the best time to announce my retirement. But considering the amount of love I have received all over, the easy thing would be to walk away from here, and the harder thing would be working hard for nine months and try to play another IPL. It will not be easy on the body, but it will be my gift (to the fans). The first game, everyone was chanting my name. My eyes were full of water, I needed to take some time off in the dugout. I realised I need to enjoy this," Dhoni said.
And, folks, that's it. Another season of Dhoni, and no retirement for now. Calling the curtains now, thanks for being with us for over 32 hours now.
CSK Vs GT Live: Awards Time
The moment everyone has been waiting for – MS Dhoni's speech. Is this it? Will we see him on the 22 yards as a player, ever again? We might find out very shortly.
CSK Vs GT Live: Incredible Premier League, Indeed!
2010. 2011. 2018. 2021. 2023.
Five years, five titles, one team and one skipper. Gujarat has been painted in yellow, or perhaps, the entire country has been. MS Dhoni's team has now won five titles, and this one could be the most special of the lot, given how they overcame innumerable difficulties.
What an extraordinary tournament this has been!
CSK Vs GT Live: Chennai Win
STOP THE PRESS! MS DHONI IS A FIVE-TIME IPL-WINNING SKIPPER!
Ravindra Jadeja is Chennai's hero. Fans in the stadium and across the world, those who have waited for over 30 hours, could not have asked for a better end to the tournament.
10 runs needed from 2 balls, and Jadeja came up trumps with a six and a four. Spare a thought for Mohit Sharma though, for bar those two deliveries, he did not put a foot wrong this season.
