Couldn't disagree more with some in this thread regarding the penalty.
I thought it was incredibly lame and petulant by Dyer to start an argument about it in a cup final and he has brought nothing but shame and embarrassment on himself and perhaps by association on his club.
He acted like a spoilt child and if I was manager I'd have subbed him there and then, do not pass Go and do not collect £200.
If you are not the designated penalty taker then you have no right whatsoever to demand a penalty and I found the whole incident incredibly unprofessional not to mention unsavoury. I was sat there waiting for Ashley Williams to come running up (since there was a delay to sub the keeper on) and sort it out, but it seemed to fall to the likes of Michu to be peacemaker.
I can understand him perhaps asking to take it but it is a privilege not a right, acting all Billy Bigshot and throwing his toys out of the pram means he has fallen through the floor in my estimation. It went on far too long and left a sour taste in the mouth, evoking memories of Drogba in the last game of the season a year or two back when he was chasing the golden boot.
edit: The thing is as well is that it was De Guzman who was denied the goalscoring opportunity in the first place, brought down when faced with basically an open goal. Had it been Dyer who was robbed by the foul I could maybe have a smigeon of sympathy for his position, but in this situation it is nothing short of a disgrace.
