According to the "Aspen" report, with the continuous evolution of the tactical system, coaches have also put forward new demands for full-backs. As a result, full-backs have become two of the three positions with the highest average transfer fees in the summer transfer market.
The full-back position has never received much attention in the transfer window, but this situation is changing. According to TransferRoom data, right-back and left-back are two of the three positions with the highest average transfer fees in the summer transfer market, second only to wingers. Specifically, left-backs saw the largest increase in average transfer fee compared to the previous transfer window (139%), followed by wingers (94%) and right-backs (86%).
The role of full-backs has changed in recent years. As well as the traditional quick-crossing full-backs, the football world has adapted to new roles. Liverpool under Klopp promoted Alexander-Arnold to the core of the team's system, while Guardiola brought important changes by inverting the concept of full-backs, and Arteta also followed this idea, using players such as Zinchenko and Skelly.
Last season, Paris Saint-Germain led by Luis Enrique won the Champions League. Nuno Mendes and Achraf became key figures, which further enhanced the value of full-backs. Historical experience shows that champions often lead the way, and perhaps it is from here that the value of full-backs is re-evaluated.
