The City striker turned defender is currently away with the Black Stars squad training in Accra, and will be determined to try to convince Ghana coach Akwasi Appiah to take him to Brazil.
"I'm buzzing for Jeff," Moore told the Leicester Mercury. "He's absolutely top-class and he's worked so hard for this opportunity, what with having to adjust to a new position.
"To be called into the 26-man squad is a huge pat on the back for him.
"He's a really good friend of mine. I'll be calling him up in the next few days to get all the gossip on how it's going.
"I have every belief in him, and if he shows the kind of form he's shown for us recently, he will do brilliantly.
"We were in Thailand when he found out (about the call-up), and I knew he was hoping for a call so I was hovering around him to find out.
"Then his phone went and he had the biggest smile on his face, he was so happy.
"He was over the moon, all the lads are so proud of him.
"The ones who have been to major tournaments before, like Marcin Wasilewski, came over to speak to him, and just told him that if he makes the 23-man squad, to enjoy every moment of it because it's a great experience. We're all hoping that he makes it."
