McIlroy, who lives on the same street as Donald, reported he had spoken to the former world number one about staying on for a third term in “quite a few talks before the new year”.
After the announcement, Donald told BBC Sport that he wanted to take some time after the last Ryder Cup to enjoy the victory, which came under a dramatic backdrop due to the highly charged atmosphere in New York.
McIlroy reported “it’s a massive part of your life” so he understood why Donald wanted to take his time over committing for 2027.
“It’s a big time commitment. He puts a lot into it, but he’s put his golf career on hold for six years to do this,” reported the Northern Ireland player.
“He has to feel like everything else that’s going on is right, and Diane [Donald’s wife] has to be into it. The kids have to be into it and it’s a lot more than just his decision at the end of the day.”
McIlroy reported he was determined to play a key role at Adare Manor, the first time he would play a Ryder Cup on the island of Ireland.
“At the end of the day, we all see the opportunity for him to go down as the greatest Ryder Cup captain ever if we can go and win in Ireland.
“I’m excited for him and for the opportunity that he has.
“I just want to be a part of that team to help him try to make that history.”
