WATCH: The oldest rule in the book! Barcelona stunned SECONDS after dramatic late equaliser at Royal Antwerp as two 17-year-olds take centre stage

Antwerp were excellent throughout the 90 minutes in Belgium, and recorded a famous win. Prodigious midfielder Arthur Vermeeren capitalised on an Oriol Romeu error to open the scoring within two minutes, before Ferran Torres equalised before half-time. Vincent Janssen netted in the 56th minute after another Romeu error, before Marc Guiu came off the bench to equalise in injury time. Amazingly, Ilenikhena then went straight up the other end to seal all three points for the Belgian side. They always say you're at your most vulnerable when you've just scored!

Barcelona have already qualified for the knockout stages, so the defeat does not dump them out of the competition but it is notable that both goals scored in injury time were netted by 17-year-olds. Guiu scored against Athletic Club earlier this season, while Ilenikhena has now scored seven goals for the Belgian side.

They have already qualified for the Champions League group stages and have gone through as group winners. It remains to be seen if the club have any chance of winning the trophy on the basis of this performance, however.
