Harry Redknapp will make a second attempt to land Kenwyne Jones with Sunderland ready to cash in on the striker.
Stadium of Light chief Sbragia blasted Redknapp's transfer window pursuit of Jones and insisted the player would stay.
The 24-year-old underlined his commitment by signing a new four-and-a-half-year contract.
But Sbragia is believed to have changed his mind about a player who has struggled since battling back from a knee ligament injury against England 10 months ago.
The turning point came when Jones - who has scored just nine goals in all competitions this season - was criticised following the 1-1 draw with Spurs last week.
Sbragia insisted his front two of Jones and Djibril Cisse "would have to do more" if Sunderland were to avoid relegation.
A Sunderland source said: "It's clear if Harry Redknapp was to come back with the same sort of money he offered in January then Sunderland would do business this summer."
Wheeler-dealer Redknapp could even get his man with a cash-plus-player deal involving Spurs misfit Darren Bent.
The 62-year-old Harry can claim his pension in three years' time but, as he prepared his team for today's clash with Aston Villa, he revealed: "I'll retire when I'm 75 - I still need the money!"
Redknapp added: "I don't know what I'd do. I love getting up at 5.30am. I really look forward to working with these players. They're a terrific bunch."
Redknapp takes his t'riffic bunch to Villa Park today for the first time since a Villa fan threw a coin at him when he was there with Portsmouth in October.
The coin hit linesman Phil Sharp above an eye, and Redknapp said: "Villa's a fantastic club and they got the idiot who threw the coin. But why should they have the hump with me? I went there with Porstmouth once and we absolutely ripped them to pieces.
"I got on the touchline, so they decided to have a go at me because we kept passing the ball to each other and kicking it in their net. Let's hope we do the same this time."
Redknapp took his men to Cheltenham on Tuesday and, unfortunately for defender Vedran Corluka, the Spurs gaffer took his son, Jamie, along too.
The Croatian revealed: "Jamie gave me the name of a horse and it lost, but it was good for team spirit - even if I did lose."
Corluka also believes that, whatever happens between now and May, the season can only be seen as a failure for Spurs.
He said: "Everyone was saying we need to be top six, so nothing we achieve this season can be seen as success because we are not where we want to be."
Sunderland's Jones urges Premiership clubs to keep ticket prices low
Sunderland striker Kenwyne Jones says Premiership clubs must keep an eye on ticket prices given the global economic downturn.
Jones said: "We cannot risk football dying as fans turn away because they can no longer afford it.
"In the current financial crisis, you still want to keep football alive.
"At Sunderland we have taken the right steps. We have recognised these times and the board and owner have eased back on the prices.
"All the times you have a signing session I like to stay for hours. The fans deserve our gratitude and it is important that as players we keep their spirits alive, make them feel it is their club. You want to give them that sort of love back. At the end of the day they keep coming back to see us."
