Martinez is quickly off his line to gather the ball at his near post. He takes out Pedro in the process and the Chelsea forward is in need of some treatment.
90+5'

64'
SHOT!
Kovacic flicks the ball around the corner for Pedro, who delays the shot. He then elects to pass to James, who does shoot but cannot find the target. It is a fair way off target.
62'
Ceballos puts his body on the line to block James' shot. Alonso then goes through Maitland-Niles in what is turning out to be a very slow-tempo half of football.
57'
Chelsea looked to spring Mason Mount through on the counter after winning the ball back quickly. Jorginho lofted a delicate pass over the top, but Mount was unable to control cleanly and Emiliano Martinez gathered.
55'
Aubameyang is the fourth player to score in the semi-final and final of same FA Cup campaign for the club, after Alan Sunderland, Frank Stapleton (both 1979) and Alexis Sanchez (2015 and 2017).
52'
Pedro puts his fresh legs to good use down the left, but credit to Holding for sticking with his man and blocking the cross. Mount's corner is an easy one for Martinez to gather.

42'

40'
Nicolas Pepe looked to hand Arsenal back the momentum shortly after. The tricky winger cleverly threaded the ball through a defender's legs before jinking on to his left boot, but he was unable to squeeze a shot away before being robbed of possession.
37'
Jorginho is handed the captain's armband in Azpilicueta's absence. Mount makes a run in behind and pulls the ball back to Jorginho, who side-foots it over the crossbar.
33'
Problem for Azpilicueta now as the captain pulls up with a hamstring problem and the early signs suggest his game is over.
