Jurgen Klopp saluted "world-class" Diogo Jota after the Portugal forward fired Liverpool into the League Cup final against Chelsea with a double in Thursday's 2-0 win at Arsenal.
Jota put Liverpool on course for Wembley with a first half strike and he clinched their berth with a late second goal in the semi-final second leg.
Jota's 13th and 14th club goals this season underlined his value at a time when Liverpool are without Mohamed Salah and Sadio Mane due to the African Cup of Nations.
"We scored two wonderful goals, Diogo Jota is on fire. We were completely convinced when he arrived at the club he would help us massively," Klopp said of the former Wolves player.
"Since he is here he has made another step, he has turned into a really world class striker."
The Reds, who last lifted the League Cup in 2012, are back in the final for the first time since 2016 as they aim to win the competition for a record ninth time.
It will be Klopp's fifth cup final with Liverpool since he took charge in 2015.
"The mood in the dressing room is over the moon. The boys were exceptional," Klopp said.
"First half, Arsenal started lively, then we calmed it down and played good football."
For Arsenal, it was a frustrating loss after they managed to grind out a 0-0 draw in last week's first leg at Anfield despite Granit Xhaka's red card.
Mikel Arteta's youthful side were exposed by battle-hardened opponents, emphasising the improvements still needed to revive the Gunners.
Thomas Partey's stoppage-time dismissal for two bookings in quick succession rubbed salt into their wounds.
"We are really disappointed but we played against a top side. We had big moments in both halves and we have to score," Arteta said.
"We had chances and were pushing for the game but we have to convert if we were too beat a team like Liverpool."
Arsenal were unable to field a team when they successfully asked for last weekend's north London derby against Tottenham to be postponed.
But Arteta sent out close to a full strength side just days later as fit-again trio Takehiro Tomiyasu, Emile Smith Rowe and Martin Odegaard all returned.
Caoimhin Kelleher replaced Alisson Becker in goal for Liverpool and quickly repaid Klopp's faith with a superb save in the fifth minute.
- Deadly Jota -
Alexandre Lacazette's free-kick was headed for the top corner until Kelleher scrambled across to tip it onto the crossbar.
But Klopp's men cut through the Arsenal defence to take the lead in the 19th minute.
Roberto Firmino's deft backheel found Trent Alexander-Arnold in midfield and his raking pass reached Jota on the left flank.
Cutting inside to the edge of the Arsenal area, Jota's impudent nutmeg took him past Tomiyasu and, with three defenders arriving in a vain attempt to block, the Portugal forward scuffed a low shot that trickled past slow to react keeper Aaron Ramsdale.
Arsenal had a golden opportunity to equalise immediately after the interval when Albert Sambi Lokonga's lofted pass sent Lacazette clear on goal, only for the French striker to balloon his shot over the bar.
In a wide-open finale, Liverpool substitute Takumi Minamino saw his shot blocked on the line by Ben White before Gabriel Martinelli's rising drive forced a good stop from Kelleher at the other end.
Jota settled it when he ran onto Alexander-Arnold's pass and chipped Ramsdale in the 77th minute.
The goal was subject to a lengthy VAR check for offside, but Jota and Liverpool were eventually able to celebrate their place at Wembley.
