Liverpool boss Jurgen Klopp disagreed with the decision to award Son Heung-Min's goal against his side.
Spurs and the Reds battled on Wednesday in a top of the table clash in the Premier League.
Liverpool emerged with a 2-1 win after a late Roberto Firmino goal.
Son had equalised for Spurs in the first half and looked borderline offside, but VAR ruled the goal was valid.
"For me, it is offside [the Spurs goal]," Klopp said post match.
"They watch it 20 times, but when I saw it, it is offside.
"There is nobody to blame [for the goal], the best way to defend Tottenham is to keep the ball all the time."
