'He should've been off'
Virgil van Dijk is not happy with Lucas Bergvall not being sent off before he scored the winning goal.
Bergvall clattered into Kostas Tsimikas with a late challenge in the build-up to a Liverpool chance.
The Reds would go on to miss the opportunity but the referee did not go back to hand the Tottenham youngster a second yellow.
Van Dijk made his thoughts known at the time and after the full-time whistle, he was straight to the officials to complain.
Speaking to Sky Sports, he said: "I think it was quite obvious that it was going to be a second yellow.
"It was pretty clear and of course a minute later he scored the winner.
" It is what it is, the referee made a mistake and he thinks he didn't."
Van Dijk continued: "Everyone on the sideline knows that it should've been a yellow... the fact is he should've been off.
"There's a linesman there, a fourth official there, there's VAR, and he doesn't get a second yellow."
Brilliant Bergvall
It was also an incredible night for Lucas Bergvall.
He scored his first Tottenham goal to win the game and give his side a massive chance of reaching the Carabao Cup final.
At 18 years and 341 days old, he is the youngest player to score for Spurs in the League Cup since Gareth Bale in September 2007.
If he goes on to have a career like Bale at the club, he will become a cult hero in north London.
Bergvall will remember this game for years to come.
Emotional moment
What a Tottenham debut for Antonin Kinsky.
The Czech goalkeeper only joined Spurs on Sunday and now he's kept a clean sheet against one of the best teams in Europe.
He made an incredible six saves while also punching four crosses away and looking confident on the ball.
You would have thought the 21-year-old was a seasoned shot-stopper in English football tonight.
After the full-time whistle, Kinsky was seen walking to the stands to meet his family and he looked emotional as he hugged them.
Great scenes to end what was a superb first Tottenham appearance.
HT: Tottenham 0-0 Liverpool
The half-time whistle blows.
It was a long old first half of this Carabao Cup semi-final first leg, but it's now come to an end.
Neither side has been able to break the deadlock and the game has clearly been impacted by Rodrigo Bentancur's injury.
Things started to pick up at the end of that half, so there is hope that the goals will follow after the break.
As things stand though, Liverpool will be the happier of the two teams as they'd be pleased to take a draw to Anfield.
Tottenham 0-0 Liverpool
We're seeing what this game could have been if it wasn't for the injuries we've had so far.
They took the intensity from the action, but that has started to rise in these final moments of the first half.
Cody Gakpo's strike was hit straight at Antonin Kinsky who has been pretty impressive on his Tottenham debut.
