The centre-back played a vital role for Liverpool on their route to Madrid before having an excellent game against Tottenham as Klopp's men ran out 2-0 winners and brought the European Cup back to Anfield for the sixth time.
But Matip told Bild am Sonntag: "Everyone in Liverpool has worked very hard for this.
"But Klopp is the decisive factor. He has put the team together and led it to where it is now. No question: Klopp is the mastermind of this title.
"He is a 'human catcher' who conquered the whole city of Liverpool - or maybe even whole England - with his enthusiasm. The club, the city, the team, everyone is straight behind him, unconditionally.
"It's something like Kloppomania here! Because he is how he is. Genuine and real - simply Kloppo."
Matip admitted the scenes in Madrid - and back in Liverpool - were like nothing he has ever seen before.
"It is still hard to realise," he said.
"It's simply madness what our win has triggered.
"The whole city was dressed in red when we came back from Madrid. The pure joy, like an ecstasy. These pictures will always remain in my mind. An unbelievable experience."
