It was announced midway through the January transfer window that the German midfielder would join the Bundesliga giants in summer, and Goretzka has since come out to justify his the move.
He told 'Funke Sport': "I've come to the conclusion that this is the right step now".
"The Champions League also plays a big role in my decision. Bayern start with different expectations in the Champions League, with Schalke we are always focusing on surviving the group stages".
"It was a long decision-making process, I spent a lot of time on it, and I was well prepared for the situation".
Goretzka has only made 12 apperances for Schalke in all competitions this season and will face stiff competition to break into the Bayern Munich first-team when he does finally make the move at the end of the season.
