Didn't it only take as long as it did as it was 2, 3 or 4 different reviews happening sequentially?
Had it just been the offside, it would have been a significantly quicker decision.
I was talking about before that replay.
I think when we saw the goal live, we didn't have visibility of the defender on the far side of the pitch.
The replay and freeze frame illustrated he was onside, just, when the lines briefly appeared.
For our goal?
I was watching it with Papa Lazarou and even before the first replay I'd said "...as long as Lamptey was onside..."
There wasn't much in it with the defender on the far side.
Offside isn't subject to "clear and obvious" since it's binary: on or off.
They are allowing attacking players a bit more leeway now. Thin lines and "offside by a toe" seems to have been consigned to history, thankfully.
Like you, I think, I was amazed that it wasn't ruled out at the first part - the foul on Lallana - as it seemed so blatant, and surely passed the "clear and obvious" test.
