Striker Grant Holt has joined Wigan from Norwich on a three-year deal.
The news that Holt's switch for an undisclosed fee had been completed was announced by the two clubs simultaneously on Monday evening on their respective official websites.
Regarding the capture of the 32-year-old, Wigan boss Owen Coyle told www.wiganlatics.co.uk: "This is a fantastic piece of business for us at a really good price. Grant is a proven goalscorer at every level and he will definitely bring something new to the table that we were missing in the squad."
Holt, who was the Norwich club captain, scored 78 goals in 168 appearances for the Carrow Road outfit in all competitions. He joined them from Shrewsbury in 2009 and helped them achieve back-to-back promotions in his first two seasons that took them from League One to the Premier League.
He will wear the number nine shirt for Wigan, who were relegated from the top flight last season, and is the seventh signing Coyle has made since he was appointed the club's new manager last month following Roberto Martinez's defection to Everton.
Coyle added: "There is already a great buzz about the place since the new boys have started coming through the door and this is another one that will really lift the place.
"He's been a hero to the fans at every club he's been at and I know the Norwich fans are sad to see him go, he's been one of the icons of their success in recent years. But now it's the Wigan fans' turn to enjoy him and we're all delighted he's coming on board."
Goalkeeper Scott Carson and striker Marc-Antoine Fortune are among the other new players to have arrived at Wigan this summer. Confirmation of the Holt deal has come on the same day that frontman Arouna Kone's transfer from the Latics to Everton was announced.
Norwich boss Chris Hughton told www.canaries.co.uk: "Grant was an important part of what we managed to achieve in the Barclays Premier League last season. Of course before I came to the club (last summer) I was very aware of the magnificent job he had already done in the three years prior to that as well.
"When we look back I'm sure we will all agree that to score the amount of goals he has done for the club in that time is a remarkable achievement. Myself and all of the staff certainly wish him all the best for his time at Wigan."
