A fuming Diego Simeone shoved Arsenal's sporting director Andrea Berta during the late stages of the Gunners' vital Champions League win over Atletico Madrid.
Arsenal booked their spot in the final of Europe's premier competition for the first time in 20 years on Tuesday night, with Bukayo Saka's strike meaning they won 1-0 on the night and 2-1 on aggregate.
And it was in the dying stages when Simeone approached Berta, who was seemingly entering the dugout area to ask for full-time.
Berta was seen walking from the tunnel area towards the field after the ball was headed out of play, and Simeone noticed and approached the Italian.
He was then seen to shove him, forcing the fourth official and other UEFA officials to step in and separate the two.
The situation soon clamed, with no antics from either dugout as Arsenal celebrated their victory on the Emirates pitch at full-time.
