• Ronald Araujo made a gesture which some viewers knew after being sent off
• The Barcelona defender's sudden sending-off transformed the tie against PSG
• Arsenal must recover in Munich - they can't carry the fear from Villa loss into Champions League showdown -

Fans have explained the meaning of Ronald Araujo's hand gesture after he was sent off in Barcelona's defeat by Paris Saint-Germain. 

The defender was given a straight red card after he bowled over Bradley Barcola 29 minutes into the Champions League clash.

His sending-off was a sliding doors moment as Barca crumbled thereafter. Barcelona had been 1-0 up on the night and 4-2 up on aggregate, but a succession of goals gave PSG a 4-1 victory and a 6-4 aggregate win.

Araujo was furious, protesting with his team-mates in the face of referee Istvan Kovacs, but he had bundled Barcola as he hared clean through on goal. A VAR check confirmed the decision.

He performed a hand gesture as he stalked off the pitch, splaying his fingers and twisting his hand, and viewers in England wondered what it meant. 

Fortunately, football fans familiar with South American culture have arrived on the scene to explain his action. 

'It’s the South American hand gesture for stealing,' one wrote on Reddit. Araujo is Uruguayan. 

'I'd say it's also understandable in Spain, if not for the comments here I'd have thought it was universal,' another wrote.

The consensus among commenters was that Araujo thought he had been robbed, with fans in Portugal and Italy also explaining that they recognised the gesture. 

Xavi and a member of Barcelona's coaching staff were later sent off as the night descended into anarchy. 

Barcelona are no strangers to capitulations in Europe. They famously squandered a 3-0 advantage against Liverpool in 2019 in the semi-finals, losing 4-0 at Anfield.

And PSG will feel that this is some retribution for 2017. The French giants had been 4-0 up after the first leg but lost 6-1 in Spain in one of the competition's greatest-ever turnarounds.
