Curtis Davies has signed a new four-year deal with West Brom.
The 21-year-old defender impressed for The Baggies during last year's Premiership campaign, although he could not save them from relegation.
He has been heavily linked with both Arsenal and Tottenham during the summer, but West Brom boss Bryan Robson has been determined not to let him go.
Having knocked back an £8.5 million bid from Wigan, Robson has now secured Davies on a long-term basis.
The youngster has been handed a lucrative new deal tying him to The Hawthorns until 2010.
"This is great news for the club," Robson told West Brom's official website.
"Curtis was obviously disappointed about being relegated but he has underlined his character by showing he is willing to fight for the club and try to help us get promoted.
"We felt after the way he performed last season he deserved the reward of a new contract.
"The fact he has signed means he is now fully focused on trying to get the Albion back up."
Chairman Jeremy Peace also stressed how important it was for the club to keep hold of one of their most prized assets.
"We've stated on countless occasions this summer we aim to strengthen the squad - not dismantle it," he explained.
"Offering Curtis this well-deserved new contract not only underlines our intentions to retain key members of the squad but also to build for the future.
"We want to get back up to the Premier League as soon as possible and establish ourselves at that level - and Curtis has a big part to play in us achieving that."
