Wigan have made their first signing of the summer after securing midfielder Fraser Fyvie for an undisclosed fee from Aberdeen.
The highly-rated 19-year-old, who made his Dons debut at the age of 16, joins on a three-year deal.
Aberdeen had earlier on Thursday confirmed Fyvie was in talks with Wigan, and the Premier League club's manager, Roberto Martinez, is pleased to have completed the transfer.
Martinez told Wigan's official website: "I'm excited, because we are signing such a strong character and a great personality at just 19 years of age.
"He's got a tremendous future in his hands and we're all delighted that he's making such a big step forward in his career here at Wigan Athletic."
"He's a bright young man and will have a good environment here in which to develop with players that have been through similar experiences and of course our fans who I know will make him feel very welcome and allow him to develop over the coming months.
"Technically he's very gifted, enjoys playing in the midfield where he can cover large areas, he's very powerful off the ball and in possession is someone who can read the tempo of the game very well.
"Also you have to remember that for such a young player he's played a lot of games in the SPL at a high standard which shows his maturity.
"Together with the rest of the squad and, of course, the other Scottish boys in the squad he'll settle in quickly I'm sure, but he's so eager to get going and take advantage of the good experience within the dressing room."
Scotland Under 19 international Fyvie made his debut for Aberdeen at the age of 16 and played more than 50 league games for the club.
