Eric Abidal insisted that he tried his hardest to make Barcelona a better-run football club but fell short in an open letter released following his resignation as technical director on Tuesday.
Abidal, who as a player at Camp Nou became a firm favourite, rejoined the Catalans in 2018 as the successor to Robert Fernandez in the role.
But his tenure coincided with a run of mixed results for the Blaugrana and severe criticisms of the club's transfer policy, while Abidal was also questioned for a public exchange with captain Lionel Messi earlier in 2020 after appearing to criticise the team's work-rate following the departure of Ernesto Valverde.
