In the midweek VAR Review: How was John Stones onside against Arsenal? Should West Ham United have been awarded a penalty for handball by Liverpool‘s Thiago? What about Manchester City defender Ruben Dias getting a red card? And why wasn’t Crystal Palace goalkeeper Sam Johnstone sent off?


Possible offside overturn: Stones on goal

What happened: Manchester City thought they had a second goal in first-half stoppage time when John Stones headed home Kevin De Bruyne‘s free kick at the back post, but the assistant immediately raised his flag for offside. The VAR began a check to make sure the decision was correct (watch here.)

VAR decision: Goal awarded.

VAR review: It caused a great deal of discussion, but it all comes down to parallax: the difference in the apparent position along different lines of sight. It’s one of the main reasons the offside technology was introduced, to remove the problem we have in taking a picture and processing it as a 3D image. As different angles are checked, moving left to right across the pitch, parallax means the position of Stones relative to Ben White will appear to change; in reality they are always in the same place.

From the one television camera angle, it seemed certain that Stones was in an offside position; when the VAR switches to the goal-line camera, we can tell the decision is going to be much closer.
