Having posted a mammoth 205/4 in 20 overs and bundled out Aussies for 131 to register a 74-run win in the semifinal, to play their first World T20 final on Sunday against Sri Lanka.
"World Cup is definitely ours, sorry Sri Lanka, but I think it is our World Cup. The support will be more for West Indies on Sunday," Gayle said after he was awarded the man of the match for his scintillating 75 off 41 balls as Windies thrashed Australia by 74 runs in the second semifinal at Premadasa Stadium on Friday.
"We love Sri Lanka, but sorry, it is going to be West Indies all the way. The final will be a good final but We will on top, definitely," Gayle added.
West Indies have not been faring well at big tournaments, as Windies have played only 2 World T20 semifinals including the second semifinal at Colombo on Friday as they reached the WT20 final for the first time since 2008.
"We needed this victory badly and I am overall happy with the performance. Australia have been playing well so far, and to turn the table on them today was very pleasant," he added.
Talking about his innings and game plan, Gayle said he was keen on staying at the crease till the last over.
"Initially I didn't get many strikes. The key for me was to be there till the 20th over. Support from Marlon (Samuels) and (Dwayne) Bravo was good and finally (Kieron) Pollard gave us a winning total. I didn't get strike but I didn't panic, the key was to take it as it comes and be there till the end," he said.
Moreover, he added that Windies were keen on targetting other bowlers except Watson and Starc which actually worked as they were the top wicket-takers for the team.
"(Shane) Watson has been a genuine wicket-taker and (Mitchell) Starc has been bowling well up front. so we needed to target Hussey and spinner. We actually had a bit of power there and it paid off for us. I am happy with the team performance," he said.
With Windies performing very well at the moment, they start favourites. With hosts also faring well, the final will be a perfect entertainer.
