Diego Costa displayed his trademark temperament during Chelsea Legends' clash with Liverpool Legends, confronting former adversary Martin Skrtel at Stamford Bridge.
What began as a charitable encounter quickly turned heated after Skrtel executed a sliding challenge from behind.
Despite winning the ball cleanly, Costa was incensed and immediately squared up to his opponent.

The former striker became the opening player to receive a yellow card after shoving Skrtel to the ground.
During the interval, Eden Hazard, who gave a brief pitch-side interview, was questioned about Costa's behaviour.
"Of course. He is still the same, we all saw it," Hazard said.
Back in 2015, Costa escaped sanctions after allegedly treading on Skrtel during Chelsea's 3-1 defeat to Liverpool. TV replays at the time seemed to capture him lashing out at the former Reds centre-back.

Nevertheless, former referee Mark Clattenburg, who officiated the match, omitted the incident from his match report, preventing any subsequent disciplinary measures.
The fundraising fixture represented the second legends encounter between these clubs this year.
During their earlier March meeting, Liverpool secured a 2-0 victory, with Peter Crouch netting twice and delighting supporters with his signature robot dance.
Chelsea's squad featured club icons includingJohn Terry, Hazard and Costa.
Roberto Di Matteo oversees the Blues legends, whilst Liverpool's side has been managed by Ian Rush, John Aldridge, Phil Thompson, and Sammy Lee.
The match was organised to raise funds for the Chelsea Foundation and the Chelsea Players' Trust, with Liverpool confirming that all proceeds will go towards the LFC Foundation's initiatives.
Ultimately, a late goal from Ryan Babel sealed the victory, marking Liverpool's second win over Chelsea this year in Legends friendlies.
