Like any club, Celtic will have been left to rue certain transfer decisions made over the years, with one such potential Parkhead blunder having been that of former Hoops defender, Jack Hendry.

Plucked from Dundee on a £1.5m deal on deadline day back in January 2018, the centre-back went on to fail to make his mark for the Old Firm outfit, making just 27 appearances in all competitions during his time in Glasgow.

That struggle to secure a more prominent role ultimately led to a loan move to Australian outfit Melbourne City in January 2020, only for the Scotsman to suffer a serious knee injury on just his second appearance for the A-League in what was another unwanted setback in his career.

Having fallen out of favour back at his parent club under Neil Lennon, the 6-foot-5 colossus was subsequently shipped off to Belgian side KV Oostende on loan for the 2020/21 campaign, with the hope of finally beginning to rebuild his career.

The one-time Wigan Athletic man managed to do just that as he went on to enjoy a fine season during that temporary stint abroad, having been voted the best player in Belgium as a result of his stunning displays by respected outlet Sport Voetbal.

That form saw Oostende opt to activate an option to buy to sign the Glasgow-born gem for a fee of around £1.75m - albeit with Transfermarkt suggesting that the deal was at little as £990k - with the Hoops potentially taking a loss on their initial investment.

The 17-cap brute was then swiftly moved on to fellow Pro League side Club Brugge that same summer, with Sky Sports reporter Anthony Joseph suggesting that the fee was large as £8.6m.

Having already suffered the blow of seeing their former asset sold on for a relatively hefty price tag, those at Celtic Park then had to witness Hendry blossom during his time at the Jan Breydel Stadium.

The central defender particularly caught the eye during the club's Champions League voyage last season, notably managing to keep a Paris Saint-Germain forward line consisting of Kylian Mbappe, Neymar and Lionel Messi at bay in a 1-1 group stage draw.

He would go on to rack up 38 appearances in all competitions for the club during the 2021/22 campaign, including 29 league outings in which he won an impressive 68% of his aerial duels and won 66% of his total ground duels - with current Celtic man Carl Starfelt only recording 66% and 51% for the same two metrics, for example, in the league last term.

Somewhat surprisingly, the Scotland international has since been moved on loan to Serie A side Cremonese after slipping down the pecking order under new boss Carl Hoefkens, although that is seemingly not a fair reflection of what was an impressive campaign last time out.

The 27-year-old - who has been lauded as a "weapon" for his attacking threat by former boss Alexander Blessin - has also been handed a more regular role under Steve Clarke at international level of late, notably scoring in a 2-2 draw with Austria back in March.

A player who could well continue to thrive in Italy this season - and for his country - it looks as if the Hoops made a major mistake in letting him depart, particularly for such a small fee.
