Wigan have broken their transfer record by completing the £5.5m purchase of Emile Heskey from relegated Birmingham.
Heskey has played for Leicester, Liverpool, Birmingham and now Wigan
The Latics only agreed a fee with Blues for the 28-year-old at 1800 on Thursday and he signed by 1330 BST on Friday.
Heskey, a replacement for Jason Roberts who was sold to Blackburn for £3m, has put pen-to-paper on a three-year deal.
Boss Paul Jewell, who set the club's last transfer record when he paid £3.1m for Henri Camara, said: "This is a major coup for Wigan Athletic."
The Latics boss was delighted to land a striker after missing out on Andrew Johnson, who chose Everton instead when he left Crystal Palace.
He added: "I have said all along I want to bring real quality performers into this club and Emile fits into that category.
"He is the most high-profile signing this club has ever made and he has played for England, but I've not bought him for his reputation, I've bought him because I know what he can do on a football field.
"He's played over 300 Premiership games, he was a mainstay in the Liverpool and England attack for several seasons and has played and scored in both the World Cup and the Uefa Cup."
Heskey told the Wigan website: "I want to play in the Premiership like every player does, and what Wigan have achieved over the past few years is nothing short of amazing.
"I've talked to a lot of mates within the game and they have said nothing but good things about the manager and the way the club is run.
"It's always sad when you leave somewhere and I'd like to say thankyou to all the Birmingham fans, and to Steve Bruce, for all their support.
"But I'm a Wigan Athletic player now and I want to start showing everyone what I can do."
