What a summer this is shaping up to be for Chelsea.
After facing a 12-month transfer ban the Blues are hoping to make up for lost time by doing some serious business in the summer transfer window.
A lot will depend on how the club finish the Premier League season, with Champions League football being the ultimate aim.
If they can secure it, then it will open the door to plenty more summer deals.
Deals have already been completed to sign Hakim Ziyech from Ajax and Timo Werner from RB Leipzig, however they're far from done.
A number of stars have been linked with a move to Stamford Bridge in the coming months, but none will get supporters as excited as one in particular.
That man, of course, is Kai Havertz.
Speculation has been building over the future of the 20-year-old who is said to be attracting the interest of clubs such as Manchester United, Bayern Munich, Barcelona and Real Madrid.
But with Chelsea regarded as favourites to sign him, they've been handed a big boost following the end of the German season.
According to Bild, Bayer Leverkusen are demanding a fee of 100m euros (£90.6m) for Havertz.
They are, however, willing to negotiate on how the deal is formatted with bonuses and add-ons a possibility.
That has opened the door on a move to Chelsea, but only on the condition that Frank Lampard's side can secure their spot in Europe's premier competition.
Should that happen, then the German youngster could well be the latest addition to the flurry of transfer activity that's going on in West London.
GIVEMESPORT'S Phil Spencer says...
The transfer window isn't even open and we're already gripped by what is going on.
Chelsea have been quickest out of the blocks with two huge signings all-but wrapped up, and it seems that they aren't finished yet.
In fact, they're only just getting started.
If they can tie up a deal for Kai Havertz that would one heck of a coup - especially if they are beating some of Europe's biggest clubs to the punch.
Havertz has all of the potential to become one of the best players in world football.
At 20 years of age he is still learning and developing, and if Chelsea can convince him to join the club then it could bring a very bright future for both club and player.
Joining the likes of Christian Pulisic, Reece James, Callum Hudson-Odoi and Mason Mount it seems that the Blues are building a side which has the potential to dominate for many years to come.
A fee of £90million may seem like a lot at this point, but if Havertz fulfils even half of his potential then there's no doubt that the investment will pay off.
