Blackburn Rovers should have signed IK Start midfielder Anthony Annan before the Ghana star moved to Norway.

"Anthony should have gone to Blackburn," the Norwegian club's sporting director Svein Mathisen told Sky Sports.

"But he did not get a work permit so we managed to sign him. He is doing well for us and we have him on a long-term contract to 2011 - but it would not surprise us if he left in the summer."
