NADIR CIFTCI has agreed a four-year contract with Celtic following his £1.5million transfer from Dundee United.

The striker's agent and former Parkhead centre-forward Pierre van Hooijdonk opened negotiations over personal terms and conditions on Wednesday, but the deal was only completed this morning.

Ciftci becomes Celtic's fourth signing of the summer following the arrivals of Dedryck Boyata, Saidy Janko and goalkeeper Logan Bailly.

The 23-year-old Turk is likely to begin his Parkhead career under suspension, though, with an SFA hearing planned for July 20.

Ciftci faces charges of biting Dundee's Jim McAlister in the final Dundee derby of the season and could be hit with a lengthy ban.

The Ladbrokes Premiership champions confirmed his signing on their website this morning.

"CELTIC are delighted to confirm the signing of striker Nadir Çiftçi. The forward has arrived from fellow Scottish Premiership side Dundee United, putting pen to paper on a four-year deal at Celtic Park," said a statement.
