It appeared hard for Spurs to fight back, with Liverpool's coach Jurgen Klopp retreating to defensive approach in the last 20 minutes of the fascinating clash to guard his hitherto 1-0 lead.
Pochettino's side then had the chance to go in front from the penalty spot, but Harry Kane missed, although Liverpool felt the penalty should not have been given due to an offside.
And yet the cheers stuck in the throats as referee Jon Moss - who entered lengthy consultation with his assistant before finally awarding the first Spurs penalty - waited as Van Dijk tangled with substitute Lamela, looking towards his colleague once more before pointing to the spot. Klopp confronted Moss on the pitch at full-time and still hadn't calmed down when he spoke to the media. "It was clear offside, unbelievable, I don't know what they were discussing", Klopp said of the first penalty.
Tottenham dominated the open 10 minutes of the second half which saw Son slip through on goal, but his close range attempt was blocked by Karius.
Parity lasted just five minutes, though, as Salah struck at the death for what seemed to be the victor. "He (the official) wanted to be middle of interest and he is". They had to chase the game because we scored an early goal.
Palace climbed one place to 14th, while Newcastle remain 16th, just two points above the relegation zone.
You'd think both of them when they reflect on this game in 24 hours' time will say it is perhaps a fair result.
Of his side's chances against Mauricio Pochettino's men, Klopp said: "We could beat Tottenham". After discussion, the officiating team made the correct decision and awarded the penalty, which Kane buried. "Everyone who watched tuned in for an fantastic game from both teams". I don't think that is a penalty and the same with the first one. They couldn't get anything into him, and I think he went around 12 minutes without touching the ball.
"Sometimes you complain about them, me no because I decided a long time ago to stop complaining about referees".
