Matteo Guendouzi left Arsenal following a bad relationship with the manager and the fans which has only gotten worse since his first loan departure in 2019. However, the Frenchman has recently taught Edu a valuable lesson that has benefitted the Gunners.
The midfielder left the north London side on a permanent deal at the start of the summer transfer window as Marseille activated the obligation-to-buy clause in his loan that was agreed upon ahead of the previous season. A permanent fee was settled at £9 million which was certainly below his value after the successful season he had.
Arsenal certainly would have generated more funds for the midfielder if they prevented putting an option-to-buy clause in his loan contract. Edu has seemed to learn from this during the current transfer window, which could benefit the Gunners in the future.
