Miguel Guillen resigned on Friday as president of Seville's Real Betis, accepting "the entire responsibility for the poor planning" that has left the club facing relegation.
He announced his resignation at a shareholders meeting.
Guillen noted that when he became club president, in June 2011, Real Betis was mired in the second division and on the verge of bankruptcy.
"In three seasons, we climbed to the first division ... and we managed to qualify for a European competition," he said.
Betis now sits in last place in La Liga, with a total of 22 points and a record of 5 wins, 7 ties and 18 defeats. Though the side has 8 points in the last five games, they have only eight contests left to climb out of the bottom three.
Last weekend also saw Betis eliminated from the Europa League by crosstown rival Sevilla. EFE
