Barkley, Scout's top rated recruit in the 2009 class, said he was surprised by the news, but is happy to see Sarkisian get an opportunity to be a head coach.
"I was surprised, I didn't really expect that. I think it was good for Sark that he is moving on and becoming a head coach," Barkley said. "I think it's great for him.
"I talked with him a lot at games and at practices. I got to know him pretty well. He was one of the coaches that I was the closest with."
Surprisingly, Barkley hasn't been contacted by any other schools since Sarkisian's departure.
"No. I think people know that I am a Trojan," said Barkley, who hasn't wavered since making his commitment last January.
The strong-armed quarterback recently spoke with Pete Carroll about the coaching change and is confident that Carroll will find a capable replacement.
"He just reassured me that it's all good, and I have nothing to worry about," Barkley said. "They aren't changing the offense.
"I have faith that whoever he chooses to replace Sark will do a great job and we will continue the winning tradition."
The leading candidate at the moment is USC wide receiver coach John Morton.
"I like Morton a lot. He's a great coach," Barkley said. "He's been with some of the best coaches and athletes in America, and if he is the guy, that would be great."
Barkley wrapped up his senior season at Mater Dei HS just weeks ago, but is already looking forward to starting his college career.
"I will be enrolling early. Starting on January 12th I will be taking classes at USC.
"I think it's going to be a good head start for me. I will get some credits out of the way, starting learning the offense and get comfortable with college life."
The highly touted quarterback will officially visit USC this weekend.
