Giorgos Giakoumakis does not come across as a boy short on a bit of belief.

And the Greek striker will fancy that having made his mark in the latter half of last season that he has to have a firm grip of a starting jersey at Celtic next season.

His summer break has yet to start. A fabulous lead and impressive header for his country meant that Greece became the first team to secure promotion in the Nation’s League as they defeated Kosovo.

Giakoumakis picked up from where he signed off from domestic duty with Celtic with an audacious bicycle kick in the swashbuckling final day finale against Motherwell. If confidence is everything, Giakoumakis will fancy that his best days at Celtic are still in front of him.

Certainly, given the form he has shown over the last six months in which he claimed the mantle of joint top league goalscorer – despite effectively sitting out the opening half of the season – would suggest that a return somewhere around the 25-goal mark would not be beyond his reach this coming season.

Which leads nicely on to the dilemma that still sits on Ange Postecoglou’s desk.

Across the breadth of the clubs he has managed in domestic and international football, the Greek Australian has never once went with a traditional front pairing.

If the prospect of a front two of Kyogo Furuhashi and Giakoumkais lends itself to comparisons with a Henrik Larsson-Chris Sutton combo, it may not be an entirely plausible scenario given the Celtic manager’s leanings to how he sets his stall out.

Back in 2014 when Postecoglou was named as Australia manager he settled on a 4-2-3-1. For their Asia Cup success the following year, he operated with a 4-3-3 - the shape which led Yokahama F. Marinos to the J-League in 2019. Before then, for qualification for the 2018 World Cup, he switched to 3-4-2-1.

Furuhashi has become the central figure at Celtic since his arrival at the club. He electrifies and invigorates Celtic when he is fully fit and on it. Giakoumakis is arguably more lethal in the six-yard box where his anticipation and aggression come to the fore.

It would be wrong, though, to dismiss him as all but a physical presence as the number of one-touch finishes in among those 17 goals last season would show. Furuhashi could play wide but when he has been deployed in such a way it has blunted his offerings for Celtic.

Leon Balogun last season kept him quiet in the opening exchange of blows with Rangers at Ibrox.

Postecoglou later acknowledged he had got the set up of the team wrong. Still, with such different attacking strengths and skillsets, a two-pronged frontline fusion of Furuhashi and Giakoumakis still holds an intriguing possibility.

It will be interesting to note if it offers a change in system from the faith that Postecoglou has stuck to throughout his career.
