Jurgen Klopp saluted a “wonderful night” after creating history by leading Liverpool to the crown of world champions.
Roberto Firmino's goal nine minutes into extra time earned the Reds a 1-0 victory over Flamengo in the FIFA Club World Cup final here in Doha on Saturday evening.
It's the first time Liverpool have won the world title having lost on their previous three attempts.
In doing so, they became the first English team to win the European Cup, UEFA Super Cup and Club World Cup in the same year.
And Klopp said: “It was a wonderful night for us, for the club, for everybody who is with us.
“It's a tough period for us, but the boys, game after game after game, they really show the desire to make the next step, show the desire to win the next game, show the desire to win the next challenge.
“Tonight, we couldn't do more than win this game and winning (the title) for the first time for this wonderful club.
“Flamengo is a really, really good team and tonight we were the better team. That's why we won.”
Klopp became the first Liverpool manager to win the world title, succeeding where Bob Paisley, Joe Fagan and Rafael Benitez had previously failed.
“I said beforehand I didn't know what it would feel like, but now I can say it's outstanding,” said the Reds boss.
“Absolutely sensational. I'm so proud of the boys. Couldn't be better.
“It feels really great. We are all exhausted pretty much from a really intense game.
“In moments like this I really struggle to find the right words as it's not my native language for describing my respect for the boys and how they do it. It was an incredible performance in an incredibly difficult game against a good opponent.
“We did so many good things. So many good football moments. Everybody for different reasons was on the edge pretty much. There were some sensationally good performances.
“I'm really happy. The atmosphere in the stadium was great, Flamengo have been partying the whole week we've been here but while they can't celebrate that much now, they should be proud of what their team did.
“But we deserved the win. We were the better side. In some moments we had a really good goalkeeper, and in most other moments we were the dominant team.”
