The 32-year-old has netted 38 league goals in just 56 outings for the German giants since arriving in 2007, having bagged 47 and 50 league goals for previous clubs Fiorentina and Palermo respectively.
The prolific Italian - who is currently recovering from injury - is concerned about his first-team opportunities at the Allianz Arena earlier this summer following the arrival of Van Gaal and strikers Mario Gomez and Ivica Olic.
And as a result, Tottenham Hotspur and West Ham were linked with a move for the front-man, with Hammers boss Gianfranco Zola also tipped to land Eidur Gudjohnsen and Mario Balotelli before eventually signing Alessandro Diamanti from Livorno.
Toni recently revealed his displeasure at not being considered one of the first names on Van Gaal's team-sheet, and warned the Bundesliga outfit that he would seek a move away in January if he his services are not utlised sufficiently.
However, the striker has now pledged his allegiance to Bayern, vowing to work his way into the coach's first-team plans with next summer's World Cup in South Africa on the horizon.
"I am convinced I have the quality," he said.
"I really want to play. I am ready for the challenge.
"I want to give everything for Bayern. I want to keep scoring goals here and I think I am capable of that."
