Player values have become more and more important in the modern game.

With money running rife across the globe, fans and those working within the sport will want to know how much each player is worth.

Transfermarkt are one of the most reliable sources when it comes to tallying up the price tags and they've now provided the data for the most valuable player from the world's top 30 leagues.

Ever wondered what it would cost to sign the best player from the Croatian top-flight? Well look no further.

Let's begin!

England, Premier League - Raheem Sterling (£144m)

The Manchester City goal machine's value just continues to rise every month, putting him ahead of Sadio Mane, Harry Kane and Mohamed Salah.

Spain, La Liga - Lionel Messi (£126m)

Who else was it going to be, eh? Even at 32, the Barcelona legend is still worth an eye-watering amount of money.

Italy, Serie A - Paulo Dybala (£76.m)

Cristiano Ronaldo is beaten to the punch by his Juventus teammate, but the fact Dybala is nine years the Portuguese's junior certainly helps his cause here.

Germany, Bundesliga - Jadon Sancho (£108m)

The best teenager on the planet right now. You get the feeling Borussia Dortmund will be seeing that £108m sum or more in the near future.

France, Ligue 1 - Kylian Mbappe (£180m)

The most valuable player in the world and rightly so. A future Ballon d'Or winner and Mbappe just makes the game look so easy. He surely won't be at Paris Saint-Germain much longer, right?

Portugal, Liga NoS - Bruno Fernandes (£54m)

No wonder Manchester United are desperate to sign him. In 15 league games this season, Fernandes has seven goals and eight assists, which is why his value has continued to increase.

Russia, Premier Liga - Malcom (£36m)

Despite the fact Malcom has played just two league games for Zenit, he retains a high value due to his enormous potential - but will he ever fulfil it?

Netherlands, Eredivisie - Donny van de Beek (£49.5m)

Surprisingly, Van de Beek sits atop of the pile ahead of teammate Hakim Ziyech. The Dutchman is a baller though and is still just 22.

Argentina, Superliga - Thiago Almada (£18m)

The 18-year-old Velez Sarsfield midfielder has already made a huge name for himself, attracting interest from Manchester City. Certainly one to watch out for.

Brazil, Serie A - Everton (£31.5m)

The nippy winger excelled at the 2019 Copa America for Brazil and has attracted a lot of interest from Premier League clubs.

Belgium, Jupiler Pro League - Sander Berge (£19.8m)

The 21-year-old Norwegian midfielder was brilliant for Club Brugge in the Champions League and as a result, the European elite - including Liverpool - are watching him closely.

Mexico, Liga MX - Maximiliano Meza (£9m)

The Argentine midfielder was the surprise inclusion in the country's 2018 World Cup squad and he's now plying his trade with CF Monterrey.

Turkey, Super Lig - Abdulkadir Omur (£12.6m)

Seen by some as the future of Turkish football, the Trabzonspor midfielder has already been heavily linked with Liverpool and Man Utd.

United States of America, MLS - Josef Martinez (£15.75m)

The 26-year-old is simply too good for MLS, scoring 28 goals in 32 games for Atlanta United last season. His value represents an absolute bargain for any willing payer.

China, Super League - Yannick Carrasco (£25.2m)

Surprisingly ahead of Hulk, Oscar and Anderson Talisca, Carrasco has impressively rebuilt his career with Dalian Yifang, scoring 17 goals in just 25 games in 2019.

Japan, J1 League - Markel Susaeta (£3.6m)

That's right, the 32-year-old former Athletic Bilbao man is valued higher than Vissel Kobe duo Andres Iniesta and Lukas Podolski - fair play.

Saudi Arabia, Professional League - Giuliano (£12.6m)

The 29-year-old Brazilian is valued higher than Italian wizard Sebastian Giovinco and former Swansea striker Bafetembi Gomis.

Ukraine, Premier Liga - Viktor Tsyhankov (£18m)

Dynamo Kiev's 22-year-old midfield sensation already has seven goals in 18 league games this season. He looks a real star in the making.

Switzerland, Super League - Noah Okafor (£7.2m)

The latest teenage star to emerge at FC Basel and like many players on this list, the eyes of the European elite are firmly fixed on the 19-year-old.

Greece, Super League 1 - Konstantinos Fortounis (£9m)

The 27-year-old has been an ever-present for both Olympiakos and Greece over the past few years and is probably the division's best player.

Austria, Bundesliga - Dominik Szoboszlai (£13.5m)

With Erling Haaland and Takumi Minamino already sold by RB Salzburg, their former teammate Szoboszlai takes top spot. The 19-year-old Hungarian is quite the talent.

Croatia, 1.HNL - Dani Olmo (£31.5m)

No surprise here, with the former Barcelona youth product absolutely tearing it up out in Croatia. He will surely be the record export from 1.HNL in due course.

Czech Republic, Fortuna Lisa - Tomas Soucek (£9m)

Slavia Prague surprised everyone in this year's Champions League and 24-year-old Soucek was the key man in midfield, so no wonder he's the country's most valuable footballing asset.

Scotland, Premiership - Mohamed Elyounoussi (£13.5m)

Failed to make his mark at Southampton but the Norwegian has been pretty successful with Celtic so far, scoring four goals in six league games before being struck down with injury.

Denmark, Superligaen - Viktor Fischer (£5.4m)

Fischer was meant to be the next big thing from Ajax's academy, but an ill-fated move to Middlesbrough saw his career stall. He's now rebuilding it with FC Copenhagen.

Serbia, Super liga Srbije - Strahinja Pavlovic (£7.2m)

The 18-year-old Partizan Belgrade defender was being courted by clubs across Europe, but AS Monaco snapped him up back in December, before loaning him back to the Serbian giants.

Romania, Liga 1 - Florinel Coman (£4.95m)

One of the brightest prospects in Romanian football for quite some time, with the Steaua Bucharest winger scoring 10 goals in just 18 league games in 2019/20. A serious talent at just 21.

Poland, Ekstraklasa - Radoslaw Majecki (£4.5m)

The 20-year-old Legia Warsaw goalkeeper is looking to follow in the footsteps of Lukasz Fabianski and Wojciech Szczesny - he's already been linked with Arsenal.

Qatar, Stars League - Yacine Brahimi (£18.9m)

How many times was the Algerian linked with a move from Porto to the Premier League? Too many to count, but no one wanted to take the gamble and he instead settled for a transfer to Al-Rayyan.

Ecuador, LigaPro Seria A - Antonio Valencia (£3.6m)

A very familiar face. Valencia joined L.D.U. Quito and is the marquee name out in the Ecuadorian top-flight.

It seems only a matter of time before the plethora of young, lesser known talent on this list are snapped up by bigger clubs.

The likes of Berge, Almada, Olmo and more could be joining the likes of Sterling, Messi and Dybala sooner rather than later!
