Bangalore thrashed defending champions Chennai Super Kings to take the top position with 19 points in the Indian Premier League.
Gayle smashed an unbeaten 70 to pave the way for his side''s easy win and also claimed the Orange cap with a tally of 511 runs from nine games.
"Gayle has been responsible for the turnaround, he has been outstanding. Our fielding and bowling has been good as well, especially Zaheer today. With Dilshan leaving we had to try out a few things. All the departments are doing well, and even Aravind and Mithun did well today," Vettori said.
The West Indies batsman said he is enjoying the scorching form in this season of the IPL.
"This has been one of the longest runs I have ever had, in terms of consistency. The team has been tremendous, the fans as well. All the support has been great. You need to have the courage to go out there to get the job done, it is God''s gift so I am thankful. Teams are going to come with new plans at us. We were chasing a low total, one of us had to be there till the end," Gayle said.
Chennai skipper M S Dhoni blamed top-order failure for the defeat.
"If you are 4-5 down in the start, it is always difficult to catch up in this format. We tried to get a decent total on the board in the end," he said.
Dhoni was not happy with the strategy of the top-order batsmen, who went after the bowlers without reading the pitch properly.
"It was doing a bit in the first few overs, we should have delayed the attack. At the end, it started to get better.
You have to make sure you have to get some runs at least towards the end," Dhoni saiD.
