Bradley Wright-Phillips has completed his move to Southampton and is set to be unveiled by the club on Thursday.
The deal for the 21-year-old striker is rumoured to be worth somewhere in the region of £1 million, and was partly funded by Saints fan Chantelle Legg's contribution.
She was one of three fans to win a share of £350,000 for their club's transfer kitty in the Coca-Cola win a player competition, and boss George Burley has decided to invest the money in bringing the promising Londoner to the South Coast.
City have attached a substantial sell-on clause to the transfer and manager Stuart Pearce believes the deal is as good financially as brother Shaun's sale to Chelsea.
"Commercially, this is a good deal for the club but also for Bradley at this stage in his career," the Eastlands boss explained.
"Like his brother, he was a popular member of the squad and an extremely likable lad. As with Shaun, he will always be welcome back at this club."
The news will come as a welcome boost to the St Mary's faithful after a turbulent summer in the internal running of the club.
Meanwhile, new Ipswich manager Jim Magilton has expressed an interest in signing Saints stalwart Matt Oakley.
Oakley rejected the offer of a new one-year deal at the Championship outfit and could be tempted by a move to join his former Saints team-mate at Portman Road.
"I would love to get Matt here," Magilton admitted. "He is exactly what we are looking for and I'm definitely interested in him."
