The Sunderland manager has already made six signings and is on the point of wrapping up a ?12million triple swoop for Manchester United trio Wes Brown, John O'Shea and Darron Gibson, with Brown the first to put pen to paper, signing a four-year contract.
Remarkably, it has not deterred him from pursuing more incoming deals, with Vaughan travelling to the north-east this afternoon and undergoing routine medical checks, ahead of putting his name to a long-term contract at the Stadium of Light.
Double figures: Sunderland boss Steve Bruce is closing in on his 10th summer signing, nearing a deal for Blackpool's David Vaughan
The Wales midfielder, on a free transfer after turning down new terms at Blackpool in the wake of their relegation from the Barclays Premier League, was thought to be heading for Wolves, following a breakdown in talks with West Brom.
But he headed straight for Wearside after sensing that Bruce's spectacular recruitment drive could lead to a challenge for honours next season.
He will sign a contract for either three or four years and join a revamped Sunderland midfield that will offer Bruce a wealth of options, despite the loss of Jordan Henderson to Liverpool.
Gibson can expect to be a regular starter, once he has reached a compromise over his ?40,000-a-week wage demands, while Sebastian Larsson will provide width, after his free transfer arrival from St Andrew's, and Craig Gardner will be hoping for a place after costing ?5million from Birmingham.

Signed: Wes Brown

Vaughan is happy to take his chances after being widely credited with bringing the best out of Charlie Adam at Blackpool last season.
While Adam took the plaudits, and earned himself a ?7million move to Liverpool, Vaughan's industry gave him the platform to turn on the style with his range of passing.
It did not go unnoticed at the Stadium of Light, where Bruce identified the former winger's work-rate and effectiveness as a valuable addition to his midfield ranks.
Way forward: ?13million England Under 21 striker Connor Wickham is Sunderland's largest outlay so far this summer
Brown has also undergone a medical, while O'Shea looks sure to follow him to Wearside after fearing starting opportunities may become increasingly scarce at Old Trafford.
Bruce has already paid ?13million for Ipswich prospect Connor Wickham and ?2million apiece for Ahmed Elmohamady and Ji Dong-won, as well as snapping up Keiren Westwood on a free from Coventry.
