Liverpool manager Arne Slot and captain Virgil van Dijk were left fuming after Lucas Bergvall was allowed to score Tottenham's Carabao Cup semi-final first-leg winner on Wednesday. New images have shown why referee Stuart Attwell didn't give the midfielder a second yellow card, though.

Despite already being on a booking, Bergvall slid in to win the ball during as Liverpool counterattack, bringing down Kostas Tsmikas. The play continued with Liverpool advancing up the pitch but failing to capitalise.

A swift run forward for Spurs later and Bergvall himself netted the game's only goal. Believing Bergvall should have been sent off moments earlier Slot said after the game: "I think I saw Ange [Tottenham manager Postecoglou]sitting here unhappy on Sunday. People say these decisions even out. I don't agree with that but today a decision went for them. Very unlucky for us. I never thought we were going to lose this game."

He added: "I don’t think there’s any debate about that [being a second yellow card]. Every manager would prefer to get a second yellow card for the opposition than [an advantage] to finish that counter-attack."

However, footage suggests there was no chance the midfielder was going to be shown a second yellow card and ultimately sent off. It was widely believed that Attwell had decided to play advantage and would return to the foul afterwards. But this did not happen and the footage reveals why.

Attwell did not play advantage. He did not believe there was a foul at all, and never signalled his intention to take play back if Liverpool hadn't progressed forward.

Instead, after Bergvall slides in to make the tackle, Attwell can be seen pointing at the ball, indicating that the Spurs midfielder won the ball, rather than committing a foul. He did not extend his arm to indicate an advantage was being played.

The referee's decision to not issue a second yellow card for the foul wasn't an error, but rather his misjudgement in not deeming it a foul initially was the mistake. VAR doesn't have the authority to intervene in matters of second yellow cards, hence Bergvall was allowed to remain on the pitch and net the winning goal.

Van Dijk certainly felt that way. "I think our frustration was purely on the pitch and after the game," he said. "You can't do anything about it. Unfortunately for us, it ended with him scoring the winner tonight."

The Liverpool captain added: "What do you think [I was saying at full time]? It's correct [that I told him he made a mistake]. What do you think? If you think he made a mistake, then okay."
