Murray announced earlier this evening that he would be parting company with Lendl ahead of the 2018 season.
But Dimitrov, who works with Murray’s former coach Dani Vallverdu, believes they could be reunited at any point.
“It’s not their first time splitting up anyways,” Dimitrov said.
“Maybe it’s just a temporary thing.
“I don’t know what’s going on in his team.”
Murray has now twice split with Lendl but will continue to work with Jamie Delgado as he moves towards recovery from injury.
The Brit ended his season after being knocked out of Wimbledon while dealing with a serious hip problem.
But he appears to be close to a comeback after playing an exhibition against Roger Federer in Glasgow earlier this month.
And Dimitrov added that he would happily see Murray back on court – with or without Lendl.
“Obviously I can wish him only the best,” Dimitrov said.
“I hope he has a speedy recovery.
“I miss playing against him.
“I miss practicing against him.
“Hopefully has a speedy recovery, probably see him next year at some point.”
Murray said in a statement on his website: “I’m thankful to Ivan for all his help and guidance over the years, we’ve had great success and learned a lot as a team.
“My focus now is on getting ready for Australia with the team I have in place and getting back to competing.”
