Germany midfielder Leon Goretzka admits nothing he can say will ease the disappointment of the Schalke fans following his decision to join Bayern Munich in the summer.
The 22-year-old is Schalke's leading player, but has signed a four-year contract with Bayern to take effect from July 1, the Bundesliga champions announced.
Goretzka, who had been a reported target for several Premier League sides, including Liverpool, passed a medical on Thursday.
"I know that in doing this I am disappointing all of you and you will have little understanding of it," he said in a message to Schalke supporters on his Facebook page.
"Any statement I make now would not be well received by you.
"I do not want to say goodbye now because there is still the second half of the season to play.
"And anyone who knows me even a little knows that as always I will give my all. I want to take Schalke back into the Champions League and I want to win the DFB-Pokal on May 19 in Berlin."
