Granada’s head coach Tony Adams said the season had been “a disaster” after his side lost 2-1 at home to Espanyol in their final game.
Former Arsenal and England skipper Adams, who has hit the headlines for criticism of Arsene Wenger in his forthcoming autobiography, was appointed head coach until the end of the season on April 10 following the sacking of Lucas Alcaraz.
But Granada, already relegated, slumped to a seventh straight defeat under Adams to finish bottom of the table.
“This season has been a disaster, we must not make the same mistakes,” Adams was quoted on Granada’s official Twitter site.
“We have tried to do everything possible with these players to get the best of them.
“The main error this season have been the signings. The owner is aware that he has made many mistakes, but this is a long project.”
Adams insisted his role as head coach would not go beyond the end of the season when he was appointed, but his future at the club remains unclear.
The 50-year-old former Wycombe and Portsmouth boss was invited to join Granada in a consultancy role in November by the club’s president John Jiang.
Adams is vice president of the company owned by Chinese businessman Jiang, DDMC, and had been sporting director for Chinese Super League club Chongqing Dangdai Lifan.
Granada recently appointed Manuel Salvador as the club’s new sporting director.
