Barcelona ran out at the Estadi Olimpic Lluis Companys armed with a 3-2 triumph from their first meeting in Paris and when Raphinha capitalised on Lamine Yamal’s skilful approach work to fire in the opener, they had sight of the last four.

But that all changed in the 29th minute when defender Ronald Araujo was sent off for tripping winger Bradley Barcola on the edge of the area, VAR confirming the on-field decision for a red card.

PSG didn’t look back. The pressure built on the home goal and Barcelona self-imploded. Joao Cancelo, culpable for Ousmane Dembele’s goal before the break, then brought down the same player inside the box as Kylian Mbappe completed an impressive turnaround.

Xavi had hoped his Barcelona farewell would end with silverware at Wembley following a 13-game unbeaten run since he confirmed his summer departure back in January. But here he was dismissed for kicking pitchside water bottles as hopes of a fairytale ending went down the drain.

For Dembele, jeered throughout by the home supporters, this was the sort of performance which made him Barcelona’s second-most expensive signing when he joined for £135m in 2017.

When the 26-year-old moved to PSG last summer, he was earmarked as Mbappe’s replacement, but he is only just starting to replicate the attacking output required to be mentioned in the same breath as the player who, with 48 goals, has equalled Zlatan Ibrahimovic as the 10th-highest scorer in Champions League history.
