Former Newcastle United defender John Anderson has questioned how Mike Ashley will replace Chris Hughton.
Anderson, now a BBC Radio Newcastle pundit, believes the latest recruitment drive will prove difficult.
Anderson said: "Who's going to come? People are saying Martin O'Neill, but Martin O'Neill left Villa because he wasn't being backed.
"Do you think he is going to come here and work under a regime which is not going to give him money to spend?
"Apart from [Blackpool boss] Ian Holloway, Chris was probably the lowest-paid manager in the Premier League.
"Whoever comes in is going to want a lot more than Chris Hughton was on, and he is going to want assurances that there is going to be so much money available for him to go out and get players.
"Would Martin Jol come here? Maybe, because he wants to get back into English football.
"But I am sure if Martin Jol comes, he is going to want a four or five-year contract, where the other two [Pardew and Curbishley] would just be delighted to get back into the game.
