O'Driscoll was appointed as Ireland captain at just 23 years of age in 2002, when Foley was one of the senior players in the team. The move to make someone so young the skipper of the national team surprised many, but O'Driscoll says that Foley made his transition into the role easier with his guidance.
"It's appallingly sad," O'Driscoll said.
"We played an awful lot of games, he was very important to me. I think I was lucky that I got his respect early.
"And then he became very important to me from a captaincy point of view. I was given the captaincy, probably in place of him when Keith Wood was injured prior to the World Cup in 2003 and I was chosen by Eddie (O'Sullivan).
"He could have thrown the toys out of the cot but he did anything but. He became a very important leader within the team, helping me along. I think that early relationship really benefited me in that we did have mutual respect."
O'Driscoll also revealed how he first heard the news, which filtered through from a whatsapp group he has with his BT colleagues.
“We’ve a BT Whatsapp group and I saw lots of them coming in but I didn’t see the original," he said.
"I just saw ‘terrible news’, ‘that’s awful’ and I just read from the bottom up to the top and my heart nearly jumped out of my chest when I read the opening one."
