'No-one knows what is going on' with VAR, says Jamie Vardy

England striker Jamie Vardy insists there are still teething troubles with video assistant referees and that "no-one knows what is going on" when the system is used.

The English were denied victory as Italy were awarded a late penalty after referee Deniz Aytekin consulted the VAR before pointing to the spot as debutant James Tarkowski was deemed to have fouled Federico Chiesa.
