Chelsea had a very strong finish to their summer transfer window.
The early weeks of their summer revolved around the departure of Antoine Conte after two years in the hot-seat and ensuring Maurizio Sarri would be the man to lead them into 2018-19.
However, once their managerial situation was resolved, Chelsea got to work and captured Napoli midfielder Jorginho right from under Manchester City's nose for £51.3 million.
Robert Green was brought in to bolster the club's homegrown cohort, before Chelsea broke the world-record transfer fee for a goalkeeper to sign Kepa Arrizabalaga.
The club had effectively been forced to sell previous number one Thibaut Courtois and when they finally pinpointed a replacement, Real Madrid snapped him up for €35 million.
Chelsea head into 2018-19
Chelsea's final piece of business also involved Los Blancos and saw them procure underrated midfielder Mateo Kovacic, fresh from Champions League and World Cup finals.
It leaves Chelsea with a rather enviable squad going into the new Premier League season with the Blues kicking off their campaign at Huddersfield Town on Saturday.
Fans have already been given a glimpse into Sarri's philosophy with his tactics in the Community Shield, but the completion of the transfer window has finally settled everything.
Four ways they could line up
And there's a great number of ways Sarri could utilise his squad this season and it will certainly have fans excited.
Correct rotation and tactics could be the difference in their chase for the top four and particularly when they have the Europa League to contend with.
As a result, check out three ways Sarri could line up his Chelsea team this season:
The Premier League first XI
Sarri showcased this very formation during the Community Shield and the additions of Kovacic and Kepa make this a menacing line-up for any Premier League side.
The Europa League alternative
Chelsea will have a gruelling run of fixtures this season so how they rotate in the Europa League will be crucial and this XI shows they have no worries with squad depth.
Using Eden Hazard as a false nine
A divisive tactic in the past for Chelsea but a starting XI that could deliver the goods under a manager like Sarri and especially if Alvaro Morata fails to deliver.
An unlikely model for Sarri to call upon, yet a solution that looks very impressive in the Premier League and fully utilises the brilliant midfield options Chelsea have at their disposal.
The moral of the story is: Chelsea have some great options on their hands.
There are multiple ways the Blues could line up this season to ensure they return to the Champions League and guarantee they handle their Europa League commitments efficiently.
It also highlights just how much their transfer business has done for their squad depth and, in particular, their incredible-looking midfield.
Only time will tell how Sarri will cope in the Premier League and there will be very little room for error as the west London club moves on from a difficult 2017-18.
And although they haven't spent the most money or signed the most players, they've put themselves in a superb position to make the top four again.
