MADRID, Jan 22 (Reuters) - Former player Ander Garitano quit as Real Zaragoza coach on Tuesday just eight days after being appointed, citing personal problems for his resignation.'My decision, however surprising it might appear, is due exclusively to personal reasons,' the 38-year-old told a news conference. 'Given the state I am in right now I would have damaged the team and the club if I had carried on and I want to go now given that the team is in the middle of the table. 'I don't feel strong enough to face up to this challenge. I prefer another person to take over because the team needs someone who is 100 percent.' Garitano did not want to go into further detail about the reasons for his decision but denied media speculation that he had fallen out with the club directors over whether Argentine midfielder Andres D'Alessandro should be in the team. 'I'm not in the right shape. I've got an important reason for my decision. I've had no problem with anyone. All I ask for is respect for my decision.' Club president Eduardo Banres said the media reports about a dispute were untrue. 'I've been saddened by some of the articles that have been written because they are unfair and false,' said Banres. 'We thought Garitano was the best man for the job and we told him we thought he was making a mistake. No one could have imagined that this would happen.... I told him not to get weighed down by the responsibility.' Former Deportivo Coruna coach Javier Irureta is the favourite to replace Garitano, although leading shareholder Agapito Iglesias said the club had not yet talked to anyone. Garitano, who played for Zaragoza for six seasons between 1996 and 2002 and had been coaching one of the youth teams, took charge on Jan. 14 after Victor Fernandez was sacked. Zaragoza were knocked out of the King's Cup after a 4-2 loss against Racing Santander in his first game in charge but claimed their first league win in 10 outings when they beat Real Murcia 3-1 on Sunday. They are in 11th place in the table, three points above the relegation zone.
