Well, we can hardly say it was a surprise. Despite reaching the Champions League final just four months ago, Paris Saint-Germain have parted ways with Thomas Tuchel after an underwhelming start to the 2020/21 campaign.
The German boss' departure comes just days before the January transfer window, which begs the question: how will this impact their transfer strategy?
Far gone are the days where a manager had complete control of the incomings and outgoings at a club, so the plans will already be laid, though the new man will undoubtedly bring with him his own ideas.
With Arsenal on the hunt for a new backup goalkeeper, here's who they could target during the January transfer window.
Chelsea should not consider former PSG boss Thomas Tuchel if they do choose to sack current manager Frank Lampard.
Real Madrid have a plan to try and sign Kylian Mbappe from Paris Saint-Germain in the summer of 2021, which could be helped if Lionel Messi joins PSG.
Lionel Messi wants to stay at Barcelona beyond 2021 according to Joan Laporta.
Regardless of who comes through the door at Parc des Princes – and let's say we think it'll be Mauricio Pochettino – we've listed some of the moves PSG need to make over the coming month.
1. Shift the Deadwood
The French champions have got a lot of high earners on their books who really aren't getting enough of a look in with the first team to warrant their substantial cost.
If PSG are serious about their pursuit of Lionel Messi then they need to make room on the wage bill, and Julian Draxler, Juan Bernat and Thilo Kehrer should all be moved on in January while they can still demand a fee for the trio.
2. Line Up Angel Di Maria Replacement
Angel Di Maria has been a world class forward, but by the end of the season he'll be 33 years of age and the need for change is clear.
The Argentina international has arguably played the best football of his career in France, but if PSG are serious about becoming European champions then they can't be carrying a forward in the twilight of his career.
Whether the man they line up is a certain countryman of Di Maria's who is currently plying his trade in Barcelona remains to be seen, but either way they need to look to the future.
3. Sign Moise Kean Permanently
When PSG opted to take Moise Kean from Everton on loan for the season, it hardly looked a signing befitting a team that had narrowly missed out on becoming European champions, who were keen to strengthen before their next tilt at Champions League glory.
However, the loanee has performed very well in Paris, notching seven goals in 11 Ligue 1 outings.
Whether the Toffees are willing to part with the talented youngster remains to be seen, but it's certainly worth asking the question as they look to add a more youthful look to the squad.
4. Sort Out Neymar and Kylian Mbappe Contract Situations
Real Madrid's courting of Kylian Mbappe is no secret, and 90min recently revealed that Los Blancos were very confident of securing a deal for the Frenchman in the summer.
Despite not possessing the financial clout they have done in previous years, if Madrid set their eyes on a player they get their way more often than not, so PSG need to act fast if they're to secure the 22-year-old's future.
Their other main man is also a constant source of speculation. Neymar's current deal in Paris expires in just 18 months, with reports suggesting he will only sign a new deal if the club are successful in their pursuit of Messi.
Whatever happens, Neymar is of course crucial to PSG and they need to ensure he's tied down to a long-term deal soon.
5. Add Depth in the Full-Back Positions
As PSG look to trim the wage bill they may find themselves struggling for bodies in the full-back positions, especially since Thomas Meunier departed for Borussia Dortmund on a free transfer in the summer.
Last season's Champions League finalists have very little cover at right-back for Alessandro Florenzi, and even he is only on loan at the club from Serie A side Roma.
The need to strengthen the starting XI and subsequently improve the depth of the squad is clear, and the full-back positions should be the first areas they look to address.
