Former Queen’s Park amateur Andy Robertson is ranked at No.4 in a extensive study of the world’s most valuable defenders.
The Scotland captain is worth an eye-watering £78million according to CIES Football Observatory .
Robertson, 25, was signed from Hull City by Liverpool for just £8m in the summer of 2017.
His Anfield team-mate Trent Alexander Arnold (£115m) tops the list, with the fact he is still just 20 years of age a key factor.
Another Reds star Virgil van Dijk (£100m) is second, with Manchester City’s French centre-half Aymeric Laporte (£94m) in third spot.
CIES have used a new algorithm to calculate the potential price tag of the top players in Europe’s big five leagues - the English Premier League, La Liga, Serie A, the Bundesliga and Ligue 1.
The formula takes into account a swathe of variables such as age, their contractual status, minutes on the pitch, goals, international status and their club’s results.
In the overall rankings – factoring in every position – PSG superstar Kylian Mbappe has been named the most valuable player in the sport, with CIES suggesting that a staggering £225million would be required to tempt him away from the Ligue 1 champions.
