Arsenal fans have been reacting on Twitter to Chelsea boss Maurizio Sarri storming off during his side's training session.
The Blues were going through their final preparations ahead of the clash on Wednesday night, when David Luiz and Gonzalo Higuain appeared to clash in a drill, before the Italian, clearly agitated by the incident, stormed off the training pitch throwing his cap to ground as headed for the tunnel.
The incident is hardly ideal preparation for Sarri, who has spent pretty much the whole season battling with his stars one way or another, and has had to put up with continued rumours that his time at Stamford Bridge will come to an end following the conclusion of his side's season.
But despite Chelsea officials later telling reporters that the incidents were not believed to be related, that didn't stop Gunners fans jumping on social media to share their views on what they witnessed.
