Ankara - Werder Bremen striker Joseph Akpala has returned to Turkish side Karabukspor on a permanent deal following a successful loan stint at the club.
Akpala, 27, has put pen to a three-year deal with the Super Lig outfit after the two clubs agreed an undisclosed transfer fee.
The Jos-born frontman made 11 appearances and scored four goals for the Blue Flame last season, as a series of injury problems hampered his first-team involvement.
However, the Nigeria international is confident his injury problems are a thing of the past.

He told BBC Sport: "Sadly, things didn't work out with Werder but these things happen in football.
"My injury problems are over now and I am in a great shape for the coming season, which is a positive sign.
"I can only stay positive. Keep working hard and if I can carry that into the season then I will have a good campaign.
"The club will be competing domestically here in Turkey and in the Europa League, a very big motivation to fight hard and make a significant impact as well."
Prior to joining Werder Bremen in 2012, Akpala donned the colours of Club Brugge, Charleroi and Bendel Insurance FC.
