Ref isn't there to provide entertainment for the armchair masses. He's there to enforce the laws.
Denying a clear goal scoring opportunity = red card. Doesn't matter whether it's in the first or last minute.
I ask myself how biased you are when you write that.
I wonder what you would have said if what happened with Koscielny would have happened with Kompany.
But that are "if's"...useless
Personally i don't blame Dean at all (not even for his blatant mistake concerning Kompany's red card).
I somehow blame the rules and the y way they enforced generally.
It's true that Dean isn't there to guarantee entertainment, but one could ask if this should not be an important factor in all what refs decide. Football is entertainment and if the rules or the way they are enforced, kill the entertainment then there is something wrong.
Do i mean Dean's decision concerning Koscielny ? No, not at all. I agree with his decisions. The factis that 10 different refs will all treat fouls within the box different.
Take a foul no matter what foul that isn't blatant. The same foul in the middle of the pitch will be sanctioned in 95% of the cases by the ref. In the box: hardly. Where is the difference ? A foul is a foul.
Because refs generally tend to overlook minor fouls in the box, players like Koscielny take the risk and try to commit fouls, even blatant fouls like the one Koscielny committed.
If the every ref would give a penalty (and the subsequnet red card is perhaps not that important, a foul like the one Koscielny committed should not result in a sending off, the rules are wrong there) forevery single foul in the box, then Koscielny would not even have tried to commit that foul...
Refs and the people who adjust the rules should think about that. Yesterday's match as aspectacle was effectively over after the sending off...and it happens more and more...
