Goal picks the 15 best deals the past 10 years – excluding frees – taking a player's price, performance, success and sell-on value into account
Getty ImagesAlisson: Roma to Liverpool (€72m)
He might have become the most expensive goalkeeper of all time when he signed from Roma, but Alisson has backed up his enormous price tag since arriving from Italy.
Arguably the missing piece of the Jurgen Klopp jigsaw, the Brazilian shot-stopper has given the Reds some much-needed assurances at the back and played a big part in their Champions League triumph last season.
Ending his first Premier League campaign with 17 clean sheets and the golden gloves too, Alisson's price tag has quickly been forgotten by the Anfield faithful.

Since arriving from Valencia in 2010, David Silva has been at the heartbeat of Manchester City's emergence as a Premier League heavyweight.
The midfielder's adaptability and all-round play has been a cornerstone for City's success over the past decade with his influence far exceeding the €29 million it cost to bring him to the Etihad.
While often overlooked for individual awards, Silva has always been a team player and will take some serious replacing next season.
Getty ImagesJadon Sancho: Manchester City to Borussia Dortmund (€8m)
One of the most in-demand footballers in the world right now, Borussia Dortmund picked up an almighty bargain in Jadon Sancho.
Signed for just €8 million from Manchester City in 2017, Sancho has gone on to shine in the Bundesliga and has already established himself in England's national team.
The 19-year-old helped secure Dortmund the DFL Supercup earlier this year with a goal and assist in a 2-0 win over Bayern Munich – in the process cementing his status as one of the game's brightest prospects.
Sancho now looks certain to be sold in the coming months for a near nine-figure sum, making him a very shrewd investment for Dortmund.
Getty ImagesToni Kroos: Bayern Munich to Real Madrid (€25m)
Described by Zinedine Zidane as Real Madrid's "missing link" in 2015, Toni Kroos has gone on to justify Zizou's big claim and brings the side together on the pitch.
The German midfielder has helped guide Los Blancos to three Champions League crowns and one La Liga title since his arrival from Bayern Munich in 2014 for a less than sizeable fee by today's standards.
Kroos' range of passing and vision is up there with the very best in Europe and at 29, he can continue to be key for Real for years to come.
