Fabio Vieira was filmed screaming at William Saliba in frustration as footage from Arsenal training emerged online.

The duo were being filmed at London Colney as Mikel Arteta prepared the squad for the UEFA Champions League clash against Porto.

So, why did Fabio Vieira scream at William Saliba in Arsenal training? Let's take a look...

Fabio Vieira shouts at William Saliba Well, the pair were taking part in a rondo with other Arsenal players - in which the ball must be kept away from one player chasing in the middle.

Thanks to a mystery figure counting in the background, we can hear that the Arsenal players reached 14 passes without losing the ball - until Saliba made a mistake.

It was that moment - the 2:15 mark on Arsenal's official training video - which caused Vieira to scream out in frustration at the France international, as he spoiled the passing streak.

Fabio Vieira faces a fight for his Arsenal future It is no wonder Vieira wants things to go swimmingly in training, as he may well be fighting for his Arsenal future in the second half of the 2023/24 campaign.

It has been suggested that Arteta may look to sell the 23-year-old this summer amid interest in signing Oscar Gloukh from RB Salzburg.

Arsenal apparently had very high hopes for Vieira this season and expected him to truly kick on at the Emirates Stadium, although that has not been the case whatsoever.

The Arsenal No.21 has only managed to make 14 appearances in all competitions, scoring two goals.

Therefore, Vieira must impress in the remainder of this season, or else he could be sold.
