Australian Mott worked with Morgan when he took over the white-ball side 18 months ago, but the Irishman headed into retirement soon after, passing the baton to Jos Buttler.
As the man who led England's World Cup triumph in 2019, Morgan's word still carries plenty of weight and he has made some eye-catching observations about his old teammates.
Speaking to Sky Sports prior to England's 100-run loss to India in Lucknow on Sunday - their fifth loss in six games of an abject title defence - Morgan said the side were "definitely unsettled".
Responding to the idea they were simply off form, he added: "There's something else going on - there has to be".
Told of those comments, Mott said: "Eoin's entitled to his opinion. He's obviously been away (from India) for a couple of weeks with the birth of his child and he hasn't been in and around the rooms.
"But I'll certainly take that up with him and have a chat to him. We've got a really good relationship with him so if he's seeing something I'm not I'll definitely have that conversation.
"I don't think that (is the case) at all. Anyone inside our tent at the moment would say, despite our results, we're an incredibly tight-knit unit.
"I can only say, from my opinion, that the group has been incredibly strong.
Chris Woakes also stood up for the unity of the squad, telling Sky: "I can firmly say there is nothing wrong with the dressing room."
Still, things look so bad for England that they aren't even guaranteed a place at the next major 50-over global competition.
Places at the 2025 Champions Trophy, it's been revealed, will be allocated based on performances in this competition, with hosts Pakistan joined by the seven highest finishers.
With three matches to go England are still 10th and rock-bottom, behind both the Netherlands and Bangladesh.
Mott admitted he was not aware the qualification process had moved away from its previous link to world rankings until media reports which landed midway through the India defeat.
The decision was ratified by the ICC board in November 2021, when the England and Wales Cricket Board was being led by previous chief executive Tom Harrison, but the information appears to have been waylaid in transition.
Asked in his post-match press conference when he learned about the potential Champions Trophy issue, Mott said: "About an hour-and-a-half ago.
"The ICC do change the rules quite a bit with qualification but to be honest I don't think it would affect in any way the way we've played in this tournament, so it's not a big deal."
