The 30-year-old has been linked with a move to Chelsea despite head coach Jupp Heynckes' insistence nobody would be sold during the transfer window.
The deal to bring Leon Goretzka to the Allianz Arena from Schalke at the end of the season has led to further suggestions Vidal could look for a new club in 2018.
While he would not discount the idea of leaving Bayern before the start of next term, Vidal insists his most pressing goal is to win Europe's top club competition for the first time in his career.
"I hope to win the Champions League and then we'll see what happens, but at this moment I am 100 per cent at Bayern and there is no chance of changing teams."

Jerome Gondorf gave Bremen a surprise lead against Bayern on Sunday and the visitors made it 2-2 with 16 minutes to play after Thomas Muller and Robert Lewandowski had turned the match around.
Two further goals from Bayern's forward pair eventually made the victory safe and Vidal admitted they were caught cold by the way Florian Kohfeldt's side approached the game.
"They surprised us," he said. "They went out to look for the win from the first minute and that made it a bit difficult.
"But thank God, in the end, we were able to get the three points.
"We hope to be champions as soon as possible to focus 100 per cent on the Champions League."
