Murray has been without a coach since splitting from Ivan Lendl in March and US legend McEnroe has already expressed an interest in working with the 26-year-old.
"Every player would consider someone with his credentials," Murray told the BBC at the Madrid Masters.
"I like listening to him commentate and he has a lot to offer as well. It's interesting but if anything comes from it, who knows?
"When you are very competitive as a player, you are likely to be the same as a coach and that's also a benefit. He was a great player and he's always kept an interest in the game, which is important. He has a great knowledge of the sport."
McEnroe, 55, revealed his interest in hooking up with Murray on a visit to Scotland last week.
"If Andy Murray picked up the phone and asked me to coach him, of course I would think about it,” said the former world number one.
Murray begins his Madrid Masters campaign against Spain's Nicolas Almagro, who beat world number one Rafael Nadal at the Barcelona Open last month.
