Former Adelaide United and Newcastle Jets defender Watson joined the Indian side, based in Bangalore, in August for the tail end of their AFC Cup campaign.
He played the full 90 minutes in both legs of the quarter-final against Singapore’s Tampines Rovers and the semi-final against last year’s champions Johor Darul Ta’zim of Malaysia.
“To play in the final is a massive achievement for anyone,” Watson told The World Game from Doha on the eve of the game.
“To win it would be incredible and being the first Aussie to do so would add a nice touch to what has been a good AFC campaign.”
The win at home against JDT in the second leg of the semi-final, thanks largely to a brace from Indian superstar Sunil Chhetri, was arguably the finest in the club’s short three-year history, with a sellout crowd of over 21,000 watching the Blues inflict the only loss of the year in any competition on the 2015 AFC Cup winners.
“Our fans were incredible in the second leg versus JDT,” Watson said. “They helped us get over the line.”
Just making it to the final has been an historic achievement for Bengaluru, who are the first Indian side to ever make a continental final.
As such, they’ve received widespread support from the Indian football community and stars such as cricket legend Sourav Ganguly.
“The support has been unbelievable,” Watson continued.
"Support coming from other clubs in India and the general public just shows how much it means.
“For us to see that support makes us want to be even more successful.”
Watson and his teammates arrived in Doha early on Thursday morning and speaking the night before the game he said the excitement was building within the squad.
“Personally and as a team, everyone is feeling good,” he said. “(There’s) a lot of excitement around the players and all the staff.
Watson, who is living with English defender John Johnson, says he has adjusted well to life in Bangalore and football in India.
“Living with John Johnson has helped a lot,” he said. “(The) city is non-stop 24/7, so it’s something you get used to.
“Football side it has been a great start, but we need one more win.”
