Ligue 1 side Sochaux have agreed terms with Benfica to secure the services of their young Ghanaian midfielder Ishmael Yartey. The 22-year-old arrived in eastern France on Friday and is due to undergo a medical over the weekend before signing for the next four seasons, according to the club\'s website. Yartey signed for Benfica in 2009 but was loaned out to a number of clubs, including Servette in Switzerland, where he caught the eye after scoring eight times in 31 matches last season.
