When they came from behind to beat Chelsea and win the FA Cup for a record 14th time, their victory seemed to mean a lot more than qualifying for the Europa League next season, thanks to their player with Jersey number 14, Aubameyang.
It means their quarter of a century of participation in European competition will continue but more than that, amid all the gloom of these troubled and strange times, it signalled hope and optimism for their future.
This victory, coupled with the semi-final triumph over Manchester City, has wiped out the disappointment of their eighth place finish in the Premier League and has brought huge credit to their rookie boss Mikel Arteta.
Arteta and his players certainly celebrated like this was a result of huge significance. It may also help that, after falling behind to an early goal from Christian Pulisic, they overhauled Chelsea with two goals from their captain, talisman and prolific striker, Pierre-Emerick Aubameyang.
Arteta and Arsenal are trying to persuade Aubameyang to sign a new contract and a victory like this could be a strong persuader.
The defeat ruined Frank Lampard’s hopes of ending his debut season at Stamford Bridge on a high, with injuries to skipper Ceasar Azpelicueta, and Christian Pulisic coupled with a late red card to Mateo Kovacic ended any glimmer of hope. Chelsea’s Champions League place was already secure and Frank Lampard can still look back on what he has achieved with great satisfaction.
