Virgil van Dijk admitted Liverpool targeted Manchester United's vulnerability from set pieces after he scored a header from a corner on Sunday.
The Dutchman bullied Fred and Brandon Williams in the area - who were marking zonally - as the cross came in, before heading past David de Gea.
Jamie Carragher asked Van Dijk on Sky Sports after the match whether Liverpool set out to exploit United's vulnerability from set pieces.
And the Holland international revealed that they did.
He added: "We tried to find the near post and it worked. Fantastic delivery and the timing was there. I'm delighted. It's never easy - today I was marked by two opponents.
"We had chances today. We had to find a way through. You need to find the right spaces and throw your body on the line."
Liverpool had a goal ruled out following Van Dijk's opener after the Dutchman was adjudged to have fouled De Gea in the build-up.
On the decision, Van Dijk added: "I didn't jump with my hands up [on De Gea] - it's difficult.
"If VAR gives it we just have to accept it and carry on. I didn't think it was a foul. I expected it to be a goal."
Liverpool's win sees them go 16 points clear at the top of the Premier League, but Van Dijk insists the Reds stars are not getting carried away just yet.
"The title is not won yet," he said. "We won't get carried away - we cannot and we won't."
