"Really it's 31 years? Ian doesn't look that old", Klopp quipped.
The Egypt worldwide deftly headed in Liverpool's second goal at Anfield to join Ian Rush and Roger Hunt as the only players to achieve the feat for the Reds.
"A very tough team to play against at the moment and in the first half we struggled to live with their pace, energy [and] intensity".
"It's all about him and all about us, how we finish the season", Klopp said of Salah. Normally, in that situation, to be top of the goalscoring list at the end and win the Golden Boot, or whatever it's called, means you have been successful as a team, but we can't force it. It's good and impressive. "What a number. Wow!"
With 21 minutes remaining, Trent Alexander-Arnold curled a high ball from deep and Salah escaped from the attention of Nathan Ake to flick a header over over Begovic and into the net.
Salah should have doubled Liverpool's lead on 33 minutes but was denied by Cook with a superb block.
"And what a number we scored as a team in the whole season, that's insane".
"That's really good and we have to carry it on for a few games to come".
"But we can not force it; so, pass, shoot, pass, shoot, that's the normal thing to do. So we can not make a difference [between them]". "So we can still improve in this situation to use his threat and pass the ball somewhere else".
The victory rounded off a fine week for Liverpool, who booked a Champions League semi-final against Roma by beating Manchester City 5-1 on aggregate with a second-leg win at the Etihad Stadium on Tuesday.
Brazilian Firmino collected a pass inside the box from Alex Oxlade-Chamberlain, took a touch inside and then steered a shot through Simon Francis' legs and past Begovic's dive.
Salah's goal, his 30th in the league, not only increased his advantage over Harry Kane in the golden boot race, but also strengthened Liverpool's grip on a top-four finish as they re-established their 10-point cushion over fifth-placed Chelsea.
"They've shown that throughout the season and of course in the Champions League".
