Clubs "can't just buy success" and Newcastle fans are living in "dreamland" if they think they will sign top players like Kylian Mbappe, says former defender Jonathan Woodgate.
Newcastle have been linked with a host of players since being taken over in a £305m Saudi Arabian-backed deal.
Paris St-Germain forward Mbappe, Tottenham's Harry Kane and Barcelona's Philippe Coutinho have been mentioned.
Woodgate said it is already "difficult" to get players to Newcastle.
Last week, Newcastle became one of the richest clubs in the world after being sold by Mike Ashley, with comparisons being drawn with Chelsea and Manchester City who went on to achieve success after being taken over by wealthy owners.
