Research into the top players by difference between current value and fee paid for by their club reveals that Harry Kane of Tottenham is the best value player in the big-5 leagues, followed closely by Lionel Messi with Dele Ali in third.
The research by the CIES Football Observatory analysed the gaps between the current transfer value of players and the fee paid for them by their employer club. The current transfer value is calculated using a complex algorithm which now takes into account the potential level of the buying club for each player.
Lists of this kind obviously rest on a number of assumptions and the complexity of the transfer market is such that any algorithm is no more than a guide.
As an example, Antoine Griezmann of Atletico Madrid takes fourth place in the list, but, as CIES point out, “This does not take into account the €100 million buy-out clause negotiated by the Frenchman during his last contract extension.”
Unsurprisingly, the list of top players by value increase testifies to the relative wealth of the Premier League whose players take 21 of the top 50 places. It also testifies to the success of one North London club in particular – Tottenham Hotspur.
Tottenham have 4 players in the top 15 including in first and 3rd place and their success in the transfer market and bringing young players through explains the fact they are currently 2/17 with 10Bet to achieve a top four finish in the Premier League.
