Bayern Munich head into their UEFA Champions League quarter-final second leg against Real Madrid in high spirits after a 2–1 victory in the Spanish capital, a result that marked the German club's first away win against their historic rivals in 25 years. The mood at the club has been celebratory in recent weeks, with goalkeeper Manuel Neuer's 40th birthday, a record-breaking Bundesliga goal tally of 105 under coach Vincent Kompany, and the Madrid first leg all prompting widespread praise. However, club supervisory board member Karl-Heinz Rummenigge has urged caution, pointing to a sobering precedent from 2014 when a favoured Bayern side lost 4–0 at home to Madrid in the return leg after conceding only once away — a warning that early euphoria can prove costly against an opponent still capable of inflicting chaos.
