Meanwhile, @afcevan added: "I would just love someone to tell me why Trossard has received his second yellow there and Doku wasn't booked earlier in the game. The only reason I can see is because he's wearing red not blue. The blue with 115 cheating charges over it."
"So Doku is allowed to kick away the ball, but Trossard isn’t," wrote @ArsenalReport. "This is the kind of corruption at the FA that will result in dire consequences for the game in general."
@Stillmanator complained: "Incredibly annoying that Doku is not booked for the exact same thing. But also very dumb from Trossard given what we have already seen. Both things are true here. Horrible officiating but we had fair warning about how selectively this stupid rule is applied."
@Rory_Talks_Ball added: "Trossard is an idiot. But we’re now discussing whether Doku is kicking the ball away, or kicking it back to us, that’s our halftime analysis. Do you understand how stupid this rule is for football?"
