Games between Tottenham and Chelsea always seem to feature some form of controversy and Wednesday night's EFL Cup semi-final was no stranger to that.
Harry Kane's 27th-minute penalty separated the two sides at Wembley as Spurs took a 1-0 lead heading into the second leg later this month.
Whether the goal should have stood, though, is a whole 'nother story.
Kane was flagged offside after being put through by Toby Alderweireld, but play momentarily continued and Chelsea goalkeeper Kepa Arrizabalaga brought the English striker down.
Referee Michael Oliver then blew for a foul but needed VAR to confirm that A) Kane was onside and B) it was a penalty. VAR said yes to both.
As always, Kane made no mistake by beating Kepa from 12 yards out, but there has since been a lot of debate about whether the right decision was made.
Replays initially suggested he was onside, but new angles have shown his upper body was in an offside position. As we know, players can score with their head, chest and shoulders.
Mark Clattenburg has now reacted to the controversy and, writing for the Daily Mail, he said it was the right decision but made a point that no one else has.
According to the 43-year-old, the linesman who raised his flag should have kept it down and allowed VAR to do its job because it was a 'marginal offside decision'.
Clattenburg believes Premier League officials aren't helping matters and actually causing confusion by flagging for offside when it's so tight.
"I know VAR eventually got the decision right to award Tottenham a penalty and overturn the initial offside, but the officials are going about it the wrong way," explained Clattenburg.
"Assistant referees are flagging for marginal offside decisions. Why are England not following the way FIFA implemented VAR in the World Cup?
"What FIFA recommend is to keep the flag down. If a goal is scored, then the offside decision will be checked by VAR.
"Had Michael Oliver blown his whistle before Harry Kane was brought down, or Kane or the keeper had stopped when they saw the flag, then the wrong decision would have stood.
"That is why it is important to keep the flag down on marginal offside calls and allow the play to continue."
Clattenburg has made a valid point that should be addressed by the FA before VAR is properly implemented into the Premier League.News Now - Sport News
