Chelsea winger Estevao Willian outshone fellow teenage superstar Lamine Yamal in a sensational 3-0 home win over 10-man Barcelona in the Champions League.
18-year-old Estevao scored a stunning second goal after Barcelona's skipper Ronald Araujo was sent off.
Victory lifted Chelsea into the top eight of the 36-team league phase, meaning they would avoid an extra play-off round in February if they keep their position, with three further matches to play.
Meanwhile, Pep Guardiola's 100th Champions League game in charge of Manchester City ended in disappointment after the hosts lost 2-0 to Bayer Leverkusen.
Guardiola made 10 changes following their Premier League loss at Newcastle on Saturday, but the decision backfired in calamitous fashion as they fell to back-to-back defeats.
