Ok, some tweets on the Leicester goal, the offside, the technology and the camera angle. #ARSLEI

The frame is selected which shows the first point of contact on the pass by Gray.

Once this frame is "locked in," the same frame can be cross-checked on other angles.

That enables the VAR, Stuart Attwell, to check the position of players from other camera angles at that same point of play.

So the VAR was able to tell from this angle that the Arsenal defender was playing Vardy onside with his stretched leg.

However, it is important for the main VAR image to show the point the ball is being kicked for transparency.

This can offer a misleading camera angle, as was the case here. The perspective here gives the impression Vardy is further forward relative to the defender.

This changes at the point Ayoze Perez (who was onside) attempts to play the ball, as any touch would have created a new phase and made Vardy offside (he may look level with the ball on this camera angle).

So the only question now is does Perez touch the ball. And if anyone can categorically say he did you have better eyesight than I do.

In addition, Chris Kavanagh got a lot of misplaced praise for using the monitor on the Nketiah red.

1. He now has to.
2. In the PL this is merely a confirmatory process when the VAR decides it's a sure red.
3. So you won't see the ref use the montior on, say, Vardy-Mustafi.

VAR red cards this season have been:

1 professional foul
1 handball on the goalline
6 serious foul play tackles

There has been no VAR red for any kind of "stray" arm or boot that caught an opposition player.

If the referee tells the VAR he saw Vardy's boot accidentally catch Mustafi as both players fell to the ground, and there was no intent, you won't see a red.

The ref only uses the monitor on definite reds *in the opinion of the VAR*. Won't be a review for a "possible red".
