Alexandre Lacazette apologised to Arsenal teammates and fans after being sent off in defeat at BATE Borisov.
The Gunners lost the first-leg of their Europa League round 32 tie 1-0, with Lacazette being sent off late on for a stray elbow.
The France striker posted to social media:
Letting the team down like that is the worst feeling..
I should have stayed calm but it’s not always easy.. Sorry
There are still 90 minutes to play and I believe that my teammates will make it to the next round.. #COYG#Laca — Alexandre Lacazette (@LacazetteAlex) February 14, 2019
