I don't think it matters at all for the championship. Bayern Munich will easily become champions without him. Moreover, the main competitor, Borussia Dortmund, has lost their star player Haaland. If you put that on the scale, Dortmund suffers much more. Bayern also has plenty of time to look for a replacement. The name Ronaldo is mentioned several times, but I don't think it will be him. They still have very good attackers, but one more would be nice.
