Arsenal were on the wrong end of an incorrect decision... tiredness is no excuse for officials making bad calls

It wasn't a penalty.

It should never have been a penalty.

The tell-tale sign is the West Bromwich defender Kieran Gibbs, who doesn't appeal when the ball strikes the hand of Callum Chambers.

Mike Dean angered Arsenal's players by pointing to the penalty spot in favour of West Brom

Unlike at Selhurst Park, this penalty decision influenced the result as West Brom equalised

Calum Chambers was penalised for hand-ball but West Brom's Kieran Gibbs didn't even appeal

Chambers' hand is tucked into his body, not outstretched, and Mike Dean is in a good position to see that.

It means we had two live games on Sunday and both had controversial wrong calls by experienced officials.

The only defence I can offer — if there is any defence — is that referees have a lot of games over the holiday period too and can be fatigued.

I wonder if there is any coincidence that in both games the decisions were late on in the match, when tiredness can lead to mistakes?

However, they are still mistakes that shouldn't be made.

It didn't alter the score at Selhurst Park, but it did at West Brom.

Jon Moss was the man who awarded Palace's pen, but he was not the only ref to get it wrong
