Mane, who joined Liverpool in 2016 and has scored more than 120 goals for the Premier League club, was considering leaving Jurgen Klopp's side in search of a new challenge, according to reports.
"This question [about my future] I will answer after Champions League [final], if I'm staying or not," Mane, who has one year remaining on his Liverpool contract, told Sky Sports.
"What I want to say now is I am fully focused on the Champions League and winning it, which is far more important for me and the Liverpool fans.
"That is the answer I must give before the final. But come back to me on Saturday and I will give you the best answer you want to hear, for sure. It's special. I will give you all you want to hear then."
The 30-year-old underlined his full commitment to Liverpool for the final.
"I will do everything absolutely possible to win the game for Liverpool," Mane said.
"I think we all forgot about what happened in [the] 2018 [final]. For sure Real Madrid were the better team then and deserved to win the game, but it is going to be a different game [now]."
Speaking in his prematch news conference, Liverpool coach Jurgen Klopp dismissed speculation about Mane's future in the strongest possible terms
"The Bayern Munich rumours, I couldn't care less," Klopp said. "In this moment we are all fully focused on this game and Sadio is completely focused on this game. He knows exactly how important it is to him and how important it is to us.
"No concerns, completely normal. It is not the first time in my career that before a decisive game a Bayern Munich rumour is coming up. I don't know exactly what I did that it happens but no problem at all."
