Bergvall escaped a second yellow card for a foul on Kostas Tsimikas and, just two minutes later, stroked home from Dominic Solanke’s lay-off.
The goal means Spurs have one fit in the final ahead of the second leg at Anfield on February 6.
Very convincing debut from the Czech goalkeeper, whose distribution was an instant hit with the Tottenham fans and just what was needed. Made a remarkable late save to deny Darwin Nunez.
Pushed up high on the right wing. Missed a glorious chance in the second half when he dinked wide after an Alisson mistake.
You can see he is also a midfielder in the way he so bravely marauds out from the back. Brave.
Played really well, especially in the first half, skipping past challenges with tidy touches and close control.
An important stopping force to Liverpool’s attacks, putting important challenges in and scanning his surroundings constantly. Full of energy throughout. Yellow for one mistimed tackle, and fortunate to avoid red for a later foul before scoring a sensational winner.
Got beaten in a few tackles but put in a busy enough display.
An immediate injury concern after leaving the pitch on a stretcher following an eight-minute stoppage in the first half. It came after the Uruguayan went down awkwardly, face first, after stretching for an uncontested header.
Without ever impacting the game in the way he might have wanted, the Swede dropped deep to receive and could be relied upon when dribbling.
A little too slow when dribbling forward with the ball. Hooked after 72 minutes and replaced by Timo Werner.
Ran in behind, as he always will, but didn’t always get the desired service. Assisted the winner after excellent hold-up play.
