Aston Villa - The atmosphere at Villa Park was electric as Aston Villa secured a memorable victory over Bayern Munich. For the German powerhouse, this marked their first group-stage defeat since 2017, raising questions about Vincent Kompany's coaching acumen at this level. However, credit must go to Villa's manager, Unai Emery, who once again outmaneuvered Kompany, much like he did with Burnley in the Premier League last season. On Wednesday night, it was Emi Martínez who stole the show, outperforming Manuel Neuer. Just like in the 1982 European Cup final, Villa triumphed 1-0 over Bayern. The decisive goal was scored by Jhon Durán, whose first-time finish left Neuer stranded. Durán, who was almost sold in the summer, has now scored six times this season, five of which came as a substitute. The Colombian, formerly of Chicago Fire, has proven to be a valuable addition to Villa's already formidable forward line.
