Gus Poyet says Sunderland fans face another season of "panicking" unless his bosses recruit new players in January.
The Uruguayan's official role is head coach, and the job of signing players falls under the remit of owner Ellis Short and sporting director Lee Congerton.
I'm a head coach. I'm not going to be a head coach when it suits people and a manager when it doesn't.
Sunderland had to win four of their final five games last season to escape relegation, and ahead of Sunday's derby at Newcastle Poyet has told Congerton another scrap is on the cards if he does not get the new arrivals he wants.
"It’s obvious, even listening on the radio, what’s missing," Poyet, quoted in the Evening Chronicle, said. "That’s down to recruitment. I'm a head coach. I'm not going to be a head coach when it suits people and a manager when it doesn't.
"That side is recruitment, so if you get chance to ask any of the recruitment people you’re lucky, but if not, don't ask me. If we don’t get more quality, it’s going to be more of the same for the whole season – 38 games, 38 points.
"Maybe we’ll be safe with 38 but if we lose two or three games everybody will start panicking and having heart attacks. That’s not enough for me. Not after last year. We have had conversations already. It's clear. It's no problem."
High on Poyet's Christmas list is a new striker to improve his side's record of 14 goals in 16 Premier League games.
He said: "When we get into the last third the delivery needs to be better - that’s quality; the finishing needs to be better - that’s quality; the heading needs to be better - that’s quality."
