Did you not read what I posted?
I agree with you completely that Bruno should have been sent off. It wa s a straight red, no question.
However, he did it because he was deliberately trying to get himself sent off by doing something silly, rather than aggressive.
The ref could obviiously see what he was doing and decided that instead of giving him what he wanted by sending him off, a greater punishment would be to leave him on the pitch to endure his humiliation.
Thats the way I saw it at the time anyway
