Celtic have signed Nadir Ciftci from Dundee United on a four-year deal.
The Hoops had an offer for the Turkish striker accepted earlier this week, after he turned down two approaches from Wigan Athletic.
Ciftci, who is thought to be valued in the region of £1m, has now officially put pen to paper to end the long-running speculation over his future.
Manager Ronny Deila has already brought in three new faces this summer, with Dedryck Boyata, Saidy Janko and Logan Bailly all joining the Scottish champions in recent weeks.
