There's evidently a difference of opinion as to whether or not there was a deliberate movement of the arm to swat the ball away.
Out of interest, is there a caviat with handball on the line similar to where a foul tackle occurs in the box and is dogso but the referee deems it a genuine attempt to get the ball? e.g Oliver only giving a YC to Jones in the United-Chelsea Cup Final. There may be incidents where a player desperately tries to play the ball with his body but it strikes his arm which does not move towards the ball or is not in an unnatural position but prevents a goal. Would that still be a penalty and RC or only a YC in that instance, or not even a penalty?
I've seen today's incident about 3 times and am still undecided whether there was a deliberate movement of the arm after the ball diverted from the leg/thigh or whether it was in an unnatural position. But does that matter? According to the Law, is a handball in that situation an automatic penalty and RC? If so, that would seem somewhat unfair in some circumstances.
Have to agree about no Liverpool players being carded. 'Soft touch' is all very well but Fabinho could easily have seen yellow for either PI, or the late challenge in the 2nd half on its own.
It was certainly a frantic start to the game at a very fast pace and Anthony Taylor perhaps should have stamped his authority on it sooner.
