Kevin-Prince Boateng described new Barcelona teammate Lionel Messi as the "best player in the world" during his unveiling at the Camp Nou.
The Ghana international completed a shock loan move to the La Liga champions on Monday.
Boateng, 31, joined Barca on loan from Serie A side Sassuolo for the rest of the season, with an $9 million purchase option included.
The former AC Milan and Tottenham midfielder said it was a "dream" to get an opportunity to play for Barca.
"I'm very happy. It's a big honor to be here and have the possibility to play for this great club," Boateng told Barca TV.
"For every kid who starts to play football I think it is a dream to play for a club like Barcelona, so for every player and especially for me it's a big dream come true."
About the Catalan club's iconic number 10, Boateng was effusive in his praise: "The best player is Messi - in the entire world.
"It's the truth. He's the best player in this world — in every world. He's showed why in the last 10 years.
👍 @KPBofficial is unequivocal: "The best player is #Messi — in the entire world. Why are you laughing? It's the truth. He's the best player in this world — in every world. He's showed why in the last 10 years."— FC Barcelona (@FCBarcelona) January 22, 2019
