"A lot of people still want to see Chris Gayle out in the middle. I still have that love for the game and that passion for the game. I would love to carry on as long as possible in T20 and franchise cricket as well," he told reporters in Bangladesh. "Let's talk at 45. I think that's a good number," added Gayle, who turned 40 last year.
Though he has not appeared for the West Indies since a one-day international against India in August, Gayle kept himself open for the selection for November's Twenty20 World Cup in Australia.
"It would be nice. Like I said, the door is open for a chance. Let's see what happens." he said.
"We have some bright youngsters ahead as well. I have left the option open to hear back from them as well and see if they want the Universe Boss," he said.
Gayle played in several editions of the Bangladesh Premier League and is the tournament's highest run scorer among foreign players.
He had his debut for the current season on Tuesday with the Chattogram Challengers, scoring 23 off 10 balls, including three sixes in one over, in a narrow win against the Rajshahi Royals.
