The key word is shouldn't be but lets face it as humans we all have certain things that we were influenced to do. I fully believe that he and all other referees when a Chelsea player goes down in the box will think dive first unless the contact is a firm challenge, and we only have ourselves to blame for the poor sporting behaviour. Ivan is one of the most powerful fullbacks in Europe if not the most and goes down at slightest to no contact that should not be happening and had our players not been booked previously for simulation then we just may have gotten the pk today but that is just my opinion I feel we will have to agree to disagree on this one
