Bayern Munich, Real Madrid, Juventus and Chelsea are in one half, PSG, Atalanta, RB Leipzig and Atletico Madrid in the other. Champions, some of them on many occasions against teams relatively new to the Champions League.
The draw has left two halves which are very imbalanced. One half has 26 Champions Leagues between them, the other none.
Real Madrid have 13 Champions Leagues, Barca and Bayern have five each, Juventus two and Chelsea one. 26 Champions League titles in total. Napoli, Lyon and City are also in that half, but have not even reached the Champions League final.
