"People always say it's easier for the team with the extra man but it means the opponents stay massed in front of goal and work hard for each other. We didn't have the ingredients to make the difference.
"What made me angry was the comportment of certain players. We knew we'd lose at some point but the manner of defeat didn't please me. I didn't expect so much apathy from us and I hope it teaches us a lesson."
