The youngster said he would not leave his local team for any regular side, but admitted that the chance to join die Roten was too good to turn down
Bayern boss Jupp Heynckes snapped up the German Under-21 international on a three-year deal after the youngster impressed during a turbulent introduction to life in the Bundesliga.
Weiser only made his debut for the Koln in February and ultimately saw his side relegated to the second tier of German football after a 4-1 defeat to Bayern - after which the club's supporters set the stadium alight.
However, according to Weiser - who was also subject to an offer from Bayer Leverkusen - he was not desperate to leave his former club.
"I would not leave [Koln] for any club. [However] Playing for the best German club is a huge honour and I just had to take the chance. I can develop myself there.
Inspired by basketball heroes Lebron James and Michael Jordan, the versatile midfielder has taken the number 23 shirt at Bayern, and is keen to rub shoulders with the big-name players at the Allianz Arena.
"For a few years, I have admired all the players there. And now I can train and play with them. This is a killer! I used to live in France and was a fan of [Franck] Ribery. I am particularly pleased to play with him."
Some have questioned whether Weiser's big move has come too early for him, but the teenager has no such doubts.
"I do not understand this argument. I have a three-year pro contract and I'm currently a junior player. I can use this time to become a seasoned professional. "
