Eriksson succeeded Paulo Sousa as manager earlier this month and has been assured by the Thai consortium now in control at the Walkers Stadium that they are prepared to bankroll a promotion push.
While he has already been linked with Fulham`s Fredrik Stoor and Kyle Naughton at Tottenham, Eriksson insists he will take time to assess his squad and will not spend money if he feels he does not need to do so.
"I am quite new at this club so it will take some weeks to see if we need something," the Swede told Sky Sports News.
"I need some time, I just don't want to run around and spend money for the case of spending it.
"The owners want to get into the Premier League but I don't know yet (how much I will need to spend)."
