New Manchester United midfielder Bastian Schweinsteiger says he will face a "great challenge" in the Premier League next season.
The 30-year-old is United's third summer signing after the arrival of Memphis Depay and Matteo Darmian.
He will bring experience in Louis van Gaal's midfield ahead of a long season that will see the Red Devils involved in four competitions.
"Hi dear Bayern fans, and the South Stand in Munich," Schweinsteiger said in a Twitter video.
"I know that has been a lot of speculation about my future in recent weeks and months and I just wanted to thank you for the fantastic time we spent together.
"It started in the Olympiastadion and continued into the Allianz Arena. It was a really fantastic time and we experienced some great moments with 15 national titles, including the historic treble and other highlights.
"We are always going to have a bond and I will keep you in my heart forever.
"I also want to thank all the employees at the Sabener Strasse [training ground] for the great time we had together – unfortunately I can't name everybody, but thanks for everybody, you helped me a great deal.
"I hope you, dear fans, understand that I have chosen this path now. I think it's a great challenge and I'm looking forward to it, although I will never forget you.
"I will always hold you here [in my heart] and I hope we see each other again soon. Yours, Basti.
"Nevertheless, I would like to again gain experience at a new club.
"My destination is Manchester United. I hope you understand my decision. No one can take away the incredible journey we had together. MiaSanMia."
