The Simeone moment? Gabriel didn't impede Simeone in any way, he kept the pressure on and Simeone capitulated. And besides football is a contact sport & not all contact equates to a foul. Otherwise the Griezman challenge on Trossard should've been given as a penalty too.
The Emirates tonight has been everything Mikel Arteta has wanted from this crowd for years. He's spent his entire tenure trying to weaponise the fanbase and this was the high point of that mission. The bus welcome, the tifo, the noise, the energy. Properly hostile.
