TBF to Bravo, he shouldn't have ever been in the position our defense left him in - and i think a reckless challenge on someone bearing down on goal was better than going 2:1 down - take one for the team and hope to fight again, so to speak.
However, I've watched the replay and it was a dive, certainly not a red, so 'taking one for the team' probably wasn't in his mind, just averting a very capable threat with a reckless tackle that perhaps saved the game.
I'm a big fan of Bravo - he's done us proud more than he's let us down (Wolves at the Etihad and Diverpool at Wembley are two great saves that come to mind) and is a very capable deputy.
