My understanding is that the encroachment takes place before the penalty is taken so it then becomes irrelevant what happens afterwards. It’s like a pre-snap penalty in NFL.
Fair enough- I thought the point of encroachment was if it makes a material impact on the resulting play it comes into force. Whilst Guehi did clear the ball he was challenging Mbuemo who himself was offside so it’s just a bit rubbish
I shall make a trip to the FA’s website for more clarity *shudder*
