Marco Ruben has agreed to join Wigan, according to his Spanish club Villarreal.
The Argentinian striker, 23, has given a farewell interview with the Villarreal website, saying he was quickly able to agree terms with the Barclays Premier League club.
"I found out eight or nine days ago, and since then the club have continued with negotiations with my agent and he told me it was done and all that was needed was my signature," Ruben said.
"I am happy to take this opportunity because it is a good coach (Roberto Martinez) and a great team."
According to reports, Ruben could cost Wigan up to £7million, and he will sign a four-and-a-half-year contract upon arriving in the UK.
His signing could signal the end of Jason Scotland's unimpressive spell at Wigan since he followed manager Roberto Martinez from Swansea in the summer.
Ruben joined Villarreal from River Plate in January 2008, but he has never played for the first team, being first loaned to Recreativo Huelva for 18 months, before this year being assigned to Villarreal B, for whom he has scored nine goals this season.
