In-form winger Pulisic gave Chelsea an early lead, just 5 minutes into the game. Mount knocked the ball to Giroud and the Frenchman flicks it into the path of Pulisic, who dinks over Martinez.
27 minutes on, Aubameyang’s pace exposes Chelsea’s high line as he chased down Tierney’s pass. Azpilicueta pulls down his opponents and the referee Anthony Taylor points to the penalty spot.
Aubameyang, who scored twice in the semi-final, grabbed another 67 minutes on the clock. The Arsenal skipper glides past Christensen after being picked out by Pepe and dinks the ball over Caballero.
The Gunners have now won the FA Cup a record 14 times, two more than Manchester United and 6ix more times than the Blues.
