O'Dea took charge of Swansea for the first time at Bristol City, and the 3-0 loss could prove to be his only game at the helm with a home match against Blackburn Rovers coming up on Tuesday.
But the former Celtic defender and coach does not know whether he will be involved for that fixture, or any future game.
"No. I genuinely have walked out of the dressing room with the players directly to here [media interviews]," O'Dea said.
"The club have told me what they can, when they can, and I'm sure, once I leave here, I'll have an update on what tomorrow looks like.
"I've had to live for the last couple of weeks not knowing what the next two days bring. It's 24 hours at a time."
Former Liverpool elite development coach Matos emerged as Swansea's top target after they missed out on Kim Hellberg, who is poised to take over at Middlesbrough.
Matos, 37, has only been a head coach since taking over at Portuguese second-tier club Maritimo in June.
"Football moves on pretty quick and there's another game in a couple of days time so all my thoughts are with the players now to make sure they recover right," said O'Dea.
"There's definitely enough there to bring the club in the right direction. Now someone needs to lead that.
"The circumstances are difficult but, when you put perspective on it, working with these lads has been a pleasure."
These BBC journos can’t even get the game right for Tuesday ffs.
