Bravo Greylag.
In all honesty, I thought the knee protest had run its course because doing it for so long risks to dilute its impact. The sight of the England & West Indies players doing it before the first ball of the first test match of the summer was very powerful. Seeing it for the 100th Premier League game of the season has less of an impact. But the actions of this mob at Millwall show that I am wrong and we need to keep going.
