Arsenal manager Mikel Arteta was proud of his players for their support of the Black Lives Matter campaign ahead of their friendly with Brentford.
The Gunners wore t-shirts and took part in a kneel before kick-off to support the protests going on around the world.
Arteta said on Sky Sports' Football Show: "The thing that I like most is that it came from them.
"I got a phone call from the captain asking to do that, I spoke with the club straight away and we were very clear that we wanted to support their intentions, everyone collaborated, we created the shirt.
"It was a really strong message and it is more powerful because it comes from them. They think they have to support these types of causes."
Arteta's side are one of the first to be back in Premier League action when they visit his former club Manchester City on Wednesday.
The Spaniard is expecting the lack of home fans to be a possible decisive factor.
"I hope it is and we've seen we have got a good thing to measure what is happening with the Bundesliga at the moment," he said.
"So it is going to help. Football is passion and energy, and when you lose that things balance much more in my opinion.
"But I know how strong they (Manchester City) are, I know what they are able to do if they are all switched on on the day.
"So we have to be really well prepared to try and go there and win the game."
