Having inherited a squad from predecessor Paolo Di Canio in October, Poyet has been unable to put his own stamp on the Black Cats.
He will get that opportunity in the New Year, and he has been working hard to piece together a plan of attack.
The intention is to move quickly, giving new recruits as long as possible to settle and play as big a role as possible over the remainder of the campaign - as Sunderland scrap to preserve their Premier League status.
"January 1st is a Wednesday, it's not on the weekend, so if there are not any problems with bringing them in from abroad, they could be signed that day."
Poyet told The Echo: "My aim all the time is to do things quickly in January.
"We're having meetings practically every day and we're getting close to January now.
"January 1st is a Wednesday, it's not on the weekend, so if there are not any problems with bringing them in from abroad, they could be signed that day.
"Those are the things you need to manage. But it's not only in my hands. It's in the hands of the other people as well - the player, the other club, the transfer, the agreement and if there are other options. There are so many things involved.
"Now, as the manager, I want them in tomorrow so they could train with us for a week before the first. That would be perfection."
Poyet acknowledges that time is not on his side, with Sunderland five points from safety, but claims to have plenty of options to explore in January.
He added: "There are some deals that I would prefer not to do immediately because you need to wait. But, with waiting, you don't know if it's going to happen.
"If I have got another option, which I like and is similar, I'll do it and the other one loses his chance. If you wait and wait, you can lose six or seven games by then."
