Liverpool players took a knee around the centre circle at Anfield in a message of support following the death in police custody of African-American George Floyd in Minneapolis.
The picture featuring 29 Reds players came with the caption “Unity is strength.
Players reportedly requested the picture during training on Monday.
Manchester United’s Paul Pogba and Marcus Rashford added their voices to worldwide protests against racism.
Protests have been held after Floyd, an unarmed black man, died on 25 May after being restrained by white Minneapolis police officer Derek Chauvin, who kneeled on his neck for almost nine minutes to pin him down.
Chauvin has since been charged with his murder and sacked.
Former San Francisco 49ers quarterback Colin Kaepernick first protested against racial injustice and police brutality by kneeling down during the United States national anthem in the summer of 2016. Since then, that gesture has become symbolic to the Black Lives Matter movement.
During the past few days I have thought a lot about how to express my feelings about what happened in Minneapolis.
I felt anger, pity, hatred, indignation, pain, sadness.
Sadness for George and for all black people who suffer from racism EVERY DAY!
Whether in football, at work, at school, ANYWHERE!
This has to stop, once and for all! Not tomorrow or the next day, it has to end TODAY!
