I cast the chart when I read your question: 04 Jul 2020 TZ = -2.0 12.3700 P.M. 20e29 44n48 ASC=9Li37
In this type of question we look for the planet that first aspect Lord 10. Here, Lord 10 is Moon and its first aspect is with Mars in Aries. Aries represent England and Germany, and because Mars represent red colour I think Bayern, which nickname is "The Reds", will win the Champions League.
