The Die Roten boss, whose contract runs out in June 2013, has left his future at the club open but promises to give everything for the second half of the season
The Fohlen legend joined the Bavarian side as a trainer in 2011, taking over the coaching job from Netherlands boss Louis van Gaal.
And despite not being able to win silverware during two consecutive years, he reflected on the positive development of the club since taking charge.
"Never before in the history of the club [have] FC Bayern played a more modern and attractive kind of football," he told reporters at a press conference in Doha.
"A trainer needs his time to implement his ideas and his way of playing football. I [have now been] at Bayern for one and a half years and I think we can now harvest the fruits.
"Nothing will be changed regarding my work ethics, no matter what will happen in the summer," he concluded.
The 67-year-old also commented on Thomas Muller's outstanding form and Arjen Robben's return from injury.
"[Muller's] first half of the season was a world-class display," Heynckes told FAZ.
"I will make use of all of my professionals. Arjen has to pick up the pace, since he was out for a long time - and Thomas currently plays like he did in 2010 again."
