When teams like Man United come along, you can quickly add £20m to a player’s price knowing you’ll probably get it.
Everyone thought Watford were completely chancing their arm by telling Richarlison would cost them £50m, but the Toffees happily paid up.
You might have thought that was incredibly astute business from the bods at Vicarage Road, but Eintracht Frankfurt could be about to blow that out of the water.
Ante Rebic was one of the star’s of Croatia’s run to the World Cup final.
He formed part of an annoyingly physical and clinical front three with Mario Mandzukic and Ivan Perisic.
The Frankfurt man scored a stunning volley against Argentina following Willy Caballero’s gaffe, demonstrating exquisite technique with his right foot.
His performances continued to impress and Europe’s big clubs had already started circling long before Croatia were walking out at Moscow’s Luzhniki Stadium for the final.
With Inter seemingly locking Perisic away in a cupboard somewhere and not letting any clubs anywhere near him, Frankfurt may have proved themselves as the most streetwise club of the transfer window.
Just eight weeks ago, crucially before the World Cup, the Bundesliga side signed Rebic on a permanent basis after his loan spell for just €1.8m.
Now, both Man United and Bayern Munich have their sights set on the 24-year-old and how much are they willing to pay?
Upwards of €50m.
Frankfurt are not a club that normally see fees in that kind of ball park floating around with their players and if this deal goes through you can bet the chairman will be cracking open the Moet.
That could be a profit in the region of €50m for player they only signed a matter of weeks ago.
But there has to be someone that loses out in this deal, doesn’t there?
Well yes, Fiorentina will probably be kicking themselves that they didn’t hold out just two months longer.
Rebic was on loan from the Italian side this season and they stupidly let him slip through their grasp before seeing what he was capable of at the World Cup.
And now they’ve probably missed out on a cool €50m.
Luckily someone had the forethought on the Italian side to put in a 30-50% clause of any transfer from Frankfurt.
Perisic might have been Jose Mourinho’s number one target, tall, powerful and can head the ball, but Rebic is a more than capable second choice.
He’s got stamina for days, is a willing runner and showed during the World Cup that there’s more to his game than just good crossing.
We look forward to seeing him in the Premier League.
