Glasgow Rangers appointed Giovanni van Bronckhorst as their manager in November of 2021 and the Dutch head coach has enjoyed a successful time at Ibrox so far.
The Light Blues chief, who spent time at the club during his playing days, led the club to a Europa League final and won the SFA Cup last season, whilst he also secured Champions League group stage football – something Steven Gerrard was never able to achieve – this term.
Not all appointments have worked out for the Gers over the years, though, and one man who found life in Scotland difficult to adjust to in the hot seat was Frenchman Paul Le Guen.
He had won the Ligue 1 title with Lyon in each of his last three seasons in management prior to arriving at Rangers in 2006 and only lasted 23 Premiership matches – winning 11 and losing six – before leaving his post.
His results on the pitch left plenty to be desired and one of his first transfer decisions at Ibrox also turned out to be a huge mistake as he allowed Ross McCormack to leave for nothing.
Le Guen seemingly decided that he was not good enough for the senior squad at the time and McCormack has since gone on to enjoy an excellent career.
After joining Motherwell, the Scottish attacker moved to Wales to join Cardiff and scored 30 goals in 88 appearances for the Bluebirds before signing for Leeds United, where he racked up 58 goals and 31 assists in 157 outings.
He was then at the centre of a tug of war in the summer of 2016 as Norwich and Aston Villa, who had both been relegated from the Premier League, battled it out for his signature. The Villans ended up landing him in a deal worth up to £14m after the Canaries had offered an initial £11m.
This means that he went from leaving Rangers for nothing to being worth a sizeable sum in a short amount of time, having bagged an impressive 132 goals for Fulham, Leeds, and Cardiff combined.
Therefore, Le Guen had a disaster by allowing McCormack to leave as the club missed out on a prolific scorer and creator who went on to accumulate a hefty amount of money in transfer fees throughout his career.
Light Blues fans may look back and wonder what could have been had the attacker been shown an ounce of faith by the French manager and given a chance to impress in the Premiership.
Instead, they had to watch on as he racked up huge profits and goal tallies for his respective clubs in England and Wales.
