Absolutely no chance. He has felt contact on his back and thrown himself to the floor.
That contact being the foul, contact to the back of his leg and then a push in the back.
The red and white tints have clearly blinded your view. That is the clearest case of simulation I have seen the referees only mistake was not to caution .
As has been stated the Watford commentators also stated how blatant a penalty it is, have their red and white tints also blinded their view?
