LISANDRO MARTINEZ was extremely lucky not to receive a red card for serious foul play on Cole Palmer.
The Manchester United defender’s studs caught the Chelsea playmaker high on his left knee.
Referee Rob Jones deemed it was a yellow card for a reckless challenge — but VAR Michael Salisbury should have intervened to upgrade the punishment to a red.
Martinez endangered the safety of Palmer and knew what he was doing by stopping the attack at all costs.
The challenge occurred in stoppage time at the end of the 1-1 draw at Old Trafford.
Chelsea boss Enzo Maresca insisted during his post-match interview that it was an obvious red card offence.

In his press conference he then added: "They show me before the press conference, I think it is quite clear for all of us.
"The referee is there to make a decision, he took a different decision.
"For me, when there is no intention to go for the ball and just the player, is a red."
