Paul Pogba turning out for former club Juventus
Paul Pogba's return to Manchester United is the biggest transfer world football has ever seen.
It's been met with widespread hysteria, and provoked reaction from just about everyone within the footballing world - including some Premier League managers.
Arsenal manager Arsène Wenger labelled the fee for the Frenchman as "completely crazy," and Liverpool's Jürgen Klopp claimed that he wouldn't spend £89 million on one player even if he had the funds available to him.
The other bosses may be critical, but no doubt the new United manager José Mourinho will be feeling very pleased with the signing indeed.
And actually, from Manchester United's point of view, this transfer may have been exactly what they needed. And agreeing an initial fee of £89 million for Pogba may not be the gross overspend that some are labelling it.
Pogba in action
United needed to make a statement
Manchester United's fall from grace since the days of Sir Alex Ferguson has been unceremonious to say the least, and fans have grown frustrated by their team that has flattered to deceive on the league table and starved them of the attacking football that gets bums off the Old Trafford seats.
With the team having floundered away from the top of the table in the last couple of years and Mourinho beginning has career as United boss, it was important that the club made a statement signing to show other title contenders for this season that they mean business.
Perhaps the boost of the Pogba signing will give other players in the squad a lift and improve the performance of other places in the team. The fact that the fee has broken the world record has reassured United followers, and the wider football world, that the Red Devils are still a global footballing superpower.
He's one of football's brightest young stars
Simply put, Pogba has the potential to become the best player on the planet in the coming years. Players like these just don't come cheaply. Pogba has the ability to change games, to transform defence into attack, and to control every aspect of a football match.
He covers the field with grace at 6"4, and can be the focal point to Mourniho's new United team. His arrival takes pressure off players like Wayne Rooney, who United looked to as their talisman in the past. If he adds more goals to his game, and Mourinho should play him in a more advanced midfield position to allow him to do this, then he's well on his way to becoming a truly great player for Premier League football.
He'll be desperate to succeed
Pogba has no shortage of causes for motivation, returning to the club that he left in pretty acrimonious circumstances four years ago. He has a lot to prove to United fans, who didn't see that much of Pogba in action before he rejected a new contract at the club and joined Juventus.
And let's not forget, Pogba is now the most expensive player ever, and he's going to have to put in the performances to justify that tag. Factor in his recent disappointment with France at this summer's Euros where the hosts lost to Portugal in the final, and you sense Pogba must be itching to get back to playing football again.
He's a huge commercial asset to United
The Paul Pogba brand is building, and his face is universally recognised. How many fans do you think will be after his name for the back of their Manchester United shirt now? In an age where sponsorship deals are extortionate and United get floated around the New York stock exchange on a daily basis, it pays to bring in star names like Pogba.
At the risk of sounding a bit old-fashioned - aren't fees like this just the direction in which modern football is going? Perhaps in years from now we will look back at this transfer and see it as quite a cheap deal for United.
If Paul Pogba helps to bring Manchester United back to the top of European football, then it's highly unlikely that the United board of directors will care too much what price they payed to sign the player. And if he wins trophies at Old Trafford, then that will also go some way to refunding his transfer fee.
It's an expensive mistake to make, and if Pogba doesn't produce the performances that he is capable of then expect an extra helping of criticism for United from other clubs. But United will be praying that this transfer is not one to add to their lengthy list of expensive flops, but one that represents real value for money - despite being the most expensive fee ever paid.
