Anyone who thought transfer season would start with a whimper hasn't been paying attention.
It's all-action and Celtic are front and centre of it with supporters frantically hitting the F5 button, as they await news on loan stars Jota and Cameron Carter-Vickers sealing permanent switches.
But Ange Postecoglou is unlikely to stop there as the Australian aims to bolster his squad ahead of a first Champions League foray in five years.
Celtic have the peace of mind of guaranteed group stage football and are seeking quality additions before dining at European football's top table.
And incoming recruitment chief Mark Lawwell will lay out his vision for the future as he departs Manchester City for a return to Glasgow.
Record Sport runs the rule over the latest links with the Premiership champions.
Christopher Scott
He was one of the first names to be linked with Celtic this summer but it would be easy to overlook him amid a flurry of transfer interest.
Record Sport exclusively revealed Bayern Munich were looking for around £250,000 for the German youth international with the Bundesliga big boys were set to trigger a one-year extension.
But Football Ghana claim Bayern are poised to allow Scott to exit on a free transfer with a move to Austrian side SK Austria Klagenfurt believed to be close to completion.
Scott is a versatile midfielder in the mould of current Celtic stars, Reo Hatate and David Turnbull.
Antoine Semenyo
What a rise it has been for the 22-year-old Bristol City striker.
His dazzling displays have led to Celtic, among others, keeping close tabs on him and he has now landed his first senior call-up to the Ghana national team.
City boss Nigel Pearson is a major fan of his forward and Record Sport understands the Championship side valued their star turn at £20m back in January.
And now Semenyo is set to add to his burgeoning reputation by representing the Black Stars ahead of crucial run of fixtures.
Ryan Mmaee
The striker is on Celtic's radar and Record Sport revealed on Wednesday the Premiership champions have carried extensive data analysis on the free-scoring Ferencvaros striker.
And the Parkhead side may be set to benefit if they move for a forward who has turned heads since his move to Hungary.
Celtic's lack of qualifiers is good news with Mmaee nursing an ankle injury which ruled him out of international fixtures for Morocco.
He brings added value as he can operate both from the left and in a central position to further bolster the wealth of options Postecoglou has at his disposal.
Taylor Harwood-Bellis
Celtic were named as a potential destination for the experienced 20-year-old Manchester City defender.
He's racked up a fair amount of game time during fruitful loan spells with Blackburn, Anderlecht and Stoke City.
And his spell at Belgium might offer a clue into what comes next for the City star in the making.
Former Anderlecht boss Vincent Kompany is closing in on a switch to Burnley and will likely be in search of reinforcements.
James Tarkowski is heading for the exit door and Harwood-Bellis fits the profile of a potential replacement for the England international.
