Even without Van Dijk on the field, the quadruple-chasing Reds did not allow Chelsea a sniff in a lacklustre extra time period as the two sides went to penalties for the second time this season.
However, Van Dijk sought to play down the issue as "a little twinge" as Liverpool continue to chase an unprecedented quadruple in the latter stages of the season.
"We're going to check it out. I felt in the first half when I did a sprint in the channel after 20 minutes or something, I felt a little twinge behind my knee," Van Dijk told ITV Sport after the game.
"I played on, but in the end I thought "if they put quite fast strikers in", I can't risk it for the team and I need to trust in Joel [Matip] in this case. Hopefully it will be fine and positive mindset."
While the quick turnaround means that Salah may not be risked for the impending Premier League battle with Southampton, Klopp does not expect the attacker to miss the trip to Paris.
"We had to change Mo early but it was a precaution move. He said he felt something but could carry on," Klopp told the press.
"I have spoken to both already. Both are really Ok, it's not a big thing but we play the next game on Tuesday. They might be fine but I would be surprised. The best physiotherapy is winning football games."
Meanwhile, the hamstring injury that kept Fabinho out of the FA Cup final will not let up in time for Tuesday, but Klopp has already confirmed that the Brazilian should return for the clash with Real Madrid.
Liverpool remain three points adrift of Manchester City in the Premier League table but could find themselves six behind if the reigning champions defeat West Ham United on Sunday afternoon. body check tags ::
