The Premier League has hit out at PGMOL after a weekend of significant VAR mistakes.

In an official statement, the Premier League said: 'The Premier League sets high standards and is disappointed that PGMOL fell below those expectations last weekend.
'As a result, the Premier League requested that PGMOL review and explain a number of incidents from the recent match round.
'Following discussions with PGMOL, and yesterday’s Select Group One review meeting, we support PGMOL's views on addressing these issues to improve performances going forward.
