Mohamed Salah netted an easy penalty in the Wanda Metropolitano.
That was after Moussa Sissoko was adjudged to have handled a cross by Sadio Mane.
After a VAR check the penalty was confirmed with Salah rocketing the ball past a helpless Hugo Lloris in the Spurs goal.
And fans immediately took to Twitter to stick the boot in on Jenas.
One said: “I love hearing the pain in jenas’ voice.”
Another explained: “The way Jenas uses the players’ first names like they’re his best mates is grating already.”
“Jermaine jenas crying on bt sport,” a third said.
A fourth explained: “Think I heard Jermaine jenas’s heart break.”
Robbie Savage was not convinced in Liverpool’s first half performance though.
He explained: “I’m not sure Liverpool are playing that well.
“Spurs have come into the game since the early penalty.
“I do think it is a penalty. The way VAR is being used in the Champions League, that is a penalty.”
Tottenham boss Mauricio Pochettino opted to start with Harry Kane.
That meant semi-final hat-trick hero Lucas Moura was left on the bench.
Roberto Firmino was also given the nod by Jurgen Klopp after missing a number of matches through injury.
