Jason Denayer's spell at Galatasaray is not going smoothly so far.
As Celtic marched towards a Scottish Premiership and League Cup title in 2014/15, on loan defender Jason Denayer was a key part.
The youngster was on a season long deal loan from Manchester City, and used his spell at Celtic to his benefit.
The defender thrived playing regular football, and earned a call-up to the Belgian national team, where he remains a regular part of the squad ranked number top of the FIFA World Rankings.
He is a player the majority of Celtic supporters would have liked to see back at the club this season, but he opted for a new challenge.
Denayer ideally wanted to make it at Manchester City, but after they shelled out a huge fee to sign Nicolas Otamendi from Valencia, the writing was on the wall.
The 20-year-old instead signed with Turkish side Galatasaray on loan, but so far it is not running as smoothly as his spell at Celtic.
Galatasaray are third in the Super Lig, five points off leaders Besiktas, and last night took the decision to fire their coach Hamza Hamzaoğlu.
Denayer has struggled for game time in his preferred position at centre-back this season. He has made only four league starts, with three at right-back.
A new coach could mean new opportunities, but it could also work against him, considering Hamzaoğlu was the manager who brought him to the club.
Denayer clearly wanted a new challenge, instead of the 'safe option' of re-signing for Celtic, but considering the strong progression he made last season, and Manchester City wanting to keep him in reserve, he may well have been better off taking the decision to head back to Scotland.
