Alan Pardew is confident Newcastle will spend much of the Andy Carroll money - but he accepts Mike Ashley will not invest any of his own money.
Shefki Kuqi has since been brought in as a short-term stop gap, but many fans were disappointed the club did not have a contingency plan once Carroll departed.
Pardew, though, is confident that Ashley, who has not been a popular figure on Tyneside since taking over the club in 2007, will give him much of the money to spend on new players.
"I think Mike's made it clear that financial model that he's put in here is one where he doesn't have to go to his personal world to fund it," Pardew told Sky Sports News.
"While he is here, he wants to make it viable. We're going to use that money to build the club and have a team on the pitch.
"The most important thing is Mike's a supporter and he wants his team to be exciting and wants to get excited about the prospects of the club.
"So it's a two-fold situation here, and I'm leaning on his passion for the team to get more money out of him and use as much money as I can.
"The short of it is that we will be signing players in the summer for sure."
Newcastle sent out a statement of intent by securing midfielder Cheik Tiote on a six-and-a-half year contract on Friday, something Pardew feels is a big message to their supporters about the commitment of their owner.
"I think with any club, it's difficult to keep any players at whatever club you're at," he continued.
"We're trying to do the best we can and for our fans to have this player secured for this length of time gives us some insurance.
"And we're hoping that he (Tiote) continues to play at the level he's been at, he's been absolutely brilliant.
"To be fair to Mike he's gone and said 'lets's get this guy done,' because after Andy he wanted to make sure that he sent a message to the fans that he is here, he is keeping his eye firmly on the club and he wants to build the club. And this is a big step towards that.
"I think negotiating in the Premier League for any senior player is always complex and difficult.
"We want to keep our best players, I make it perfectly clear from a managers point of view.
"Whether we can is down to the market and to the player themselves. You want to keep your best players and you want them to stay."
