Arsenal are licking their wounds today after defeat to Brentford on Wednesday.
While Arsenal lost 3-2 to Brentford in a mid-season friendly ahead of the Premier League's restart, it was seemingly David Luiz's mistake that attracted most of the attention.
The Gunners restart their 2019-20 campaign away at Manchester City next Wednesday after the season was suspended at the beginning of March due to the coronavirus pandemic.
But they suffered a setback just a week before it all kicks off again after losing against Championship outfit Brentford in a friendly at the Emirates Stadium.
