Chelsea manager Frank Lampard has said Harry Maguire should not have been on the pitch when he scored his side's second goal in a 2-0 Premier League win on Monday after the Manchester United defender escaped a red card for kicking Michy Batshuayi.
The Video Assistant Referee (VAR) system was in the spotlight after Maguire kicked Batshuayi in the groin area in the first half.
"Maguire should have been sent off," Lampard told British media. "That's clear, and that obviously changes the game."
Maguire went on to score a thumping header in the 66th minute to seal the win.
