AS PARKHEAD raised a glass to toast this season’s title success on Saturday afternoon, two players helped themselves to a double.

Kyogo Furuhashi took his tally to 20 goals for the season - from 26 starts - and Giorgos Giakoumakis to 17.

Furuhashi spent four months of the season sidelined, his Celtic colleague had a similar spell in the treatment room. Rarely have both been fit and available at the same time this term.

It remains a source of intrigue, though, to wonder just what damage they might do if unleashed together.

There is little in Ange Postecoglou’s coaching throughout the years that would suggest he would indulge in a two-pronged attack but, of all the dilemmas to ponder over the near on two-month hiatus between now and competitive football resuming for Celtic, that will a source of much interest.

If, as expected, there is no deviation from the current system there remains some interest in just how many Furuhashi might reap if he were to stay fit.

Postecoglou spoke this weekend about the over-reliance on the likes of the Japanese striker during the opening half of the season given the lack of depth as well as the injury issues that beset the club. Had he stayed fit, Kyogo would surely have hit the 30-goal mark for the Parkhead side.

With a World Cup kicking off at the end of November and running deep into December, the schedule of games will be intense from the opening weeks of the next campaign. There are no free mid-weeks in the calendar once European and domestic dates are pencilled in.

Postecoglou has reiterated more than once since the league title was confirmed that he has only scratched the surface of what he wishes to implement at Celtic.

If this week is anything to go by with the confirmed exits of Tom Rogic and Nir Bitton, it is unlikely that the grass will grow under his feet.

He spoke on Saturday night of the fact that “80 per cent” of those who took Celtic to the title didn’t get a full pre-season under their belt.

If this summer offer scope for that to be rectified, it also gives players like Callum McGregor – with 59 appearances for club and country this term – to get a proper break, physically and mentally.

But if Postecoglou has built a strong foundation on which to build further domestic success, Champions League football will be uppermost in his planning this summer.

In that respect, the expectation this summer is that the players who arrive will be in the quality over quantity bracket. For all that Celtic boasted the best defensive record in the Premiership this season, the stats in Europe would have made the Greek-Australian wince. Twenty-eight goals conceded from 14 games suggests that the next big challenge will lie in developing a system that honours the attacking football that he favours while also lending itself to a more pragmatic approach.

The environment of the Champions League will not hesitate to dish out some bruising evenings otherwise. A combative midfielder, a Scott Brown type, could be high on the wishlist when it comes to summer plans.

And for all that there was a lack of depth at times there remain significant numbers at the club. Expect a parting of the ways in the newt few weeks as the likes of Boli Bolingoli, Albian Ajeti and Vasilis Barkas could head out.

On Saturday afternoon Christopher Jullien could be spotted hanging at the back of the gaggle of players who took their bow in front of the home support. Wandering off on his own as the celebrations slowed down, it would have been interesting to hear his thoughts on a season that has offered just 16 minutes of a Scottish Cup tie against Raith Rovers.

Postecoglou has constructed the foundations this season. What he builds next will be an interesting watch.
