RCB ended their 18-year long wait for a maiden IPL trophy.
Asked to bat first, RCB posted 190/9 on the board. While Virat Kohli was the top scorer with 35-ball 43, the likes of Rajat Patidar (26 off 16), Liam Livingstone (25 off 15) and Jitesh Sharma (24 off 10) made valuable contributions with the bat.
Defending the total, Bhuvneshwar Kumar (2-38 in 4 overs) and Krunal Pandya (2-17 in 4 overs) bowled magical spells to stop PBKS at 184/7 in 20 overs.
After the match, RCB head coach Andy Flower addressed a press conference, where he said that acquiring a lethal bowling attack in the mega auction and picking players with experience were "huge first steps" towards the historic triumph.
"The auction is a huge first step that you've got to try and get as right as possible and (as a) part of (team director) Mo's (Mo Bobat) philosophy right up front, was to distribute the value a little more equitably rather than spending too much on big-name batsmen who are, of course, very fine players," Flower told the media.
"The importance of a good bowling attack was acknowledged absolutely adamantly right at the start before the auction and we worked towards that."
The win was particularly special for star batter Virat Kohli, who has been associated with RCB since the inception of the league in 2008.
"I know after the first day of the auction, we were copping a little bit of flak. People thought that we were investing our money rather than spending it. But it meant that there was some really good value to be had on the second day," Flower said.
The former Zimbabwe captain named the players RCB added to their roster during the grand auction in Jeddah last November.
"We had the money to then spend on that value. We got guys like Bhuvi (Bhuvneshwar Kumar), Krunal (Pandya), Tim David, Romario Shepherd on that second day so that was really important," he said.
"Suyash Sharma has done really well for us — our little leg spinner. I thought he has handled himself really well through the season.
"Krunal is a big match player and a great competitor and that spell today (Tuesday) was the major difference between the teams," said Flower of Krunal Pandya, who earned the Player-of-the-Match in the final for his bowling figures of 4-0-17-2.
Flower also highlighted the importance of having players with experience competing in big matches.
"We talked about that yesterday when we were in our planning meetings and earlier this evening in the huddle before the game started. We had a good group of experienced cricketers in our team," he said.
"Guys like, obviously, Virat (Kohli), (Josh) Hazlewood, Krunal Pandya, a big part of their recruitment was their experience. Hazlewood has played in World Cup finals before. He has played in big matches and big tournaments, as has Virat.
"Krunal, this is his fourth IPL win so it was crucial recruiting them in the first place. The auction is a huge step in the right direction if you can get it right," Flower added.
According to the RCB coach, the total of 190/9 wasn't huge but they trusted their bowling attack to deliver in the title clash.
"Yes, 190 didn't seem like a huge score at this ground. As you know, like an average winning score this season is 220 or something," he said.
"I wouldn't say it was below par, because in a final to go and score 190, you've still got to play really well. We have got a good bowling attack and we trusted that the bowlers would come to the party in that second innings," he further remarked.
Andy Flower acknowledged Dinesh Karthik's role as team mentor cum batting coach. "Indian insight and knowledge in our coaching staff has been really important for this campaign this year. DK, particularly, as a mentor and a batting specialist, he's been brilliant," Flower said.
"It's quite a transition to make from playing to coaching, and he has done it amazingly well, and it's very obvious that he has had an impact, certainly on the batting group," he added.
