Dick Advocaat has confirmed Sunderland have made him an offer to stay on as head coach - and says he will give his answer next Thursday.
The Dutchman, 67, guided the Black Cats to Premier League safety with a game to spare having taken the reins on March 17, replacing the sacked Gus Poyet.
Advocaat said: "They have made me an offer, yes.
"It is in principle not so important in that way, it is also important what the club wants. Can they invest or not? That's also important to know for myself before I take that decision.
"The family has a say in this, yes, but I don't want to discuss that on a wider basis. Let's wait and see next week.
"I have said already many times, I have to discuss it and I haven't done it yet. I will start doing that next week, but I want to tell [the club] as quickly as possible.
"I have to make the decision next week, and I will tell the people from Sunderland on Thursday what I will do."
On the possibility of chairman Ellis Short splashing the cash in the transfer window, Advocaat added: "We were discussing that, but he is a very clever man. In principle, he would like more on a regular basis to become more from 10th to the better places. But you also know that you have to invest, otherwise in this league you have no chance.
"Our players have done really, really well in the last eight games, but they need an injection of fresh new players to get more competition in the squad - but not in quantity, in quality."
Advocaat, who has twice managed the Netherlands as well as Rangers, PSV, Belgium, Russia and most recently Serbia, led Sunderland to three wins and three draws in his eight games in charge this season.
Also unclear is the future of Inter forward Ricardo Alvarez after his season-long loan at the Stadium of Light, but Advocaat dismissed speculation the club have already prepared a £5m bid for Celtic midfielder Nir Bitton.
