Vincent Kompany should never have been sent off. It wasn't a blind lunging two foot tackle which could have harmed Nani. He actually goes low to corral the ball with his right instep and gets it very cleanly. There was little contact.
Chris Foy really made a royal mess. He got sold by Rooney who made the red card gesture. It was actually a fantastic tackle by one of the best centre backs in football. Between Rooney's fabulous header and Kompany's sending off, City had to endure the most horrendous two minutes, completely changing the match from a very early stage.
