Former Wigan player and manager Graham Barrow has returned to the club as a first-team coach.
The 55-year-old is reunited with Latics boss Roberto Martinez, whom Barrow signed as a player when he was manager in 1995.
"This club has always been special to me, and it really is a dream come true to return here," said Barrow, who previously worked as a coach at Blue Square Premier club Altrincham. "I've worked with Roberto in the past, and he's a bright lad with lots of ideas who is very unique in what he has to offer to the club.
"The way he had Swansea playing attractive football and getting results at the same time was magnificent."
Martinez revealed Barrow was always a first-choice member of his backroom staff.
"Graham has not only been a good mentor to me over the last 15 years, but a genuine friend, and I have often asked for his advice," he told the club`s official website. "But I have not appointed him for sentimental reasons. He is a terrific football brain, and it is wonderful to have another true Wigan man on board."
