Chelsea fans were left fuming after VAR failed to award their side the opener in the Carabao Cup final against Liverpool.
Chelsea thought they had taken the lead late in the first half at Wembley, when Raheem Sterling converted Nicolas Jackson's low cross at the back post.
The linesman raised his flag for offside to deny Sterling a goal against his former club, but replays showed that the decision was an incredible tight one.
Senegalese attacker Jackson looked to be in line with Liverpool defender Ibrahima Konate as he was played in down the right channel.

However, when the offside lines were drawn as part of the VAR review, it turned out that Jackson was millimetres offside.
To the naked eye the Chelsea man appeared to be onside, and from the camera angle used by the VAR, he still looked to be onside.
It's fair to say that Chelsea fans on social media weren't best pleased.
"That's never offside," one fan wrote, while another tweeted: "That being the only angle in a final is shocking."
One fan questioned the call: "What advantage does Jackson have? Embarrassing."
Liverpool arguably enjoyed the better of the opening period, although stand-in goalkeeper Caoimhin Kelleher had to produce a fine save to deny Cole Palme from close range.
Cody Gakpo went closest for Jurgen Klopp's side, hitting the base of the post when he met Andrew Robertson's cross with a header.
