The Brazilian defender, who was signed by the Blaugrana trainer from Sevilla in 2010, credits the 41-year-old with his development as a player and a person over the last two years
After announcing his decision to step down at the end of the current campaign, Guardiola bid a fond farewell to Camp Nou on Saturday night after watching his side rack up a 4-0 victory over city rivals Espanyol, with Lionel Messi scoring all of the hosts' goals.
The evening was all about Guardiola, though, and Adriano was quick to heap praise on the 41-year-old's attributes, both as a coach and as a man.
“It's been a very emotional night, without a doubt," the former Sevilla defender is quoted as saying by his club's official website.
"Even more so because it was a derby, and for the manager’s farewell. We can only say thank you. He brought me here and he gave me the chance to be his player.
“These two years have been very important in my career and I’ve learned a lot. I’ll remember what he’s taught me for the rest of my life. I’ve improved a lot of things on a personal and footballing level.
“I like Guardiola’s transparency. And he always tried to help you. He’s a good person and he has good character."
While Guardiola is heading for the exit door at Camp Nou, Adriano insists that he would like to remain in Catalunya amidst speculation that he might be moved on in the summer.
“My objective is to stay here," the versatile full-back declared. "I have two years left on my contract and I’m very happy to be here at Barca.
“The people have been with us all season. It’s a shame that we didn’t make it to the [Champions League] final or win the Liga, but the people know that we gave it our all. We’ll keep on fighting. We still have a very important final coming up."
Barca can ensure that Guardiola's tenure ends on a high when they tackle Athletic Bilbao in the final of the Copa del Rey at the Vicente Calderon on May 25.
