Why is Real Madrid Barcelona Bayern called Zazie Horse?

Sacma, Barcelona Real Madrid need no explanation. As for Bayern, because the strong team Bayern was not listed as an option in Sina 20 12 Champions League semi-final voting, the voting options were only Real Madrid, Barcelona, Chelsea and other teams. So Bayern called me. There is also a saying that Samaranch represents Chelsea. In other words, these four teams can't touch each other in the draw of the Champions League quarter-finals, so as to avoid the premature meeting of the strong teams.
