Bayern Munich put together a video celebrating their shared history with Inter over the years ahead of the Champions League meeting, including Lothar Matthaus and Giovanni Trapattoni.
It kicks off at San Siro at 20.00 UK time (19.00 GMT).
To mark the occasion, Bayern Munich’s social media team released a compilation highlighting the many times these clubs and cities have been united, as well as being on the opposite side.
After all, Jose Mourinho’s Inter beat Bayern Munich 2-0 in the 2010 Champions League Final to complete their Treble.
Among those who have represented both clubs, there are also Matthaus, Jurgen Klinsmann and coach Trapattoni.
