When was the last time Leeds United had a summer like this?
It's been 20-long years since they broke their transfer record, 16 years since they were last in the Premier League, and last year, they had to rely on loan signings.
This is an unprecedented time not only for the whole football world but also for Leeds in particular.
They have added Spain forward Rodrigo to their ranks and also welcomed young Germany international Robin Koch to the squad.
Their academy at Thorpe Arch now has category one status and there is an estimated £200m arriving in the club's bank account following promotion.
It seems a distant memory that Leeds were bringing players like Pawel Cibicki and Jay-Roy Grot to the club.
This isn't a side battling mid-table obscurity in the Championship anymore, it's one that farms ambitions of competition in the top half of the Premier League.
Few would put it past Leeds to do something like Wolves did, earning promotion and then going on to secure Europa League football.
This is a side who have made impressive moves in the transfer market and aren't afraid to stop.
Last month Leeds were linked with a move to bolster their midfield. Rodrigo de Paul was the name on everyone's lips, but it seems as though Lewis Cook has been forgotten about.
The Daily Star suggested a few weeks ago that the Whites were pondering a £15m swoop for the Bournemouth midfielder.
Relegated with the Cherries last term, he could be available at a cut-price this summer. It's a move that's received the endorsement of Jimmy Floyd Hasselbaink too.
The former striker was interviewed recently and spoke about Leeds' interest in Cook. In doing so, he urged Marcelo Bielsa and co to swoop for the striker.
"Lewis Cook is a really good midfield player and I can understand why Leeds want him back. He gets up and down the pitch well. Technically, he is very, very good. He would be a big plus for Leeds if he were to join," he commented.
GIVEMESPORT'S Matt Dawson says...
Leeds have a plethora of young players available to them in the middle of the park. Whether it be Robbie Gotts, Jamie Shackleton, Alfie McCalmont or Mateusz Bogusz, they aren't exactly lacking options.
As a result, it would be rather harsh on those individuals to bring a former academy player back to the Whites to feature ahead of them.
Bielsa likes working with a small squad but they'll need a few more senior professionals to bolster the ranks.
At £15m, Cook would be an absolute snip, and few know him better than at Leeds.
The 23-year-old broke through under Steve Evans, a manager Cook had a special bond with, being labelled as "stunning" four years ago.
"I love working every day with somebody as talented as him. I'm very blessed as a head coach to be able to turn up at Thorp Arch and see Lewis Cook in the building," Evans said.
"I know what it means to him playing here. This is the most gracious young man you could wish to meet - he gets player of the year and he's in my office almost in tears thanking me for the improvement we've given him in six months," he added.
Cook is thought of in high regard at Leeds and it would be a no-brainer to bring him back.
Let's just hope Bielsa likes him as much as Evans did back in 2016.
