Celtic's loan signing of John Guidetti has been approved by FIFA.

The Manchester City striker's move was agreed just before the transfer window closed on Monday night, but the relevant paperwork had not been completed in time.

Guidetti is now free to play in the Scottish Premiership, but his eligibility for the Europa League has yet to be decided.

A big success at Feyenoord on loan during 2011/12, Guidetti's development was hit by serious illness at the end of that season which caused him to miss Sweden's Euro 2012 campaign.

The 22-year-old was on loan at Stoke last season but made a minimal impact.
