Input: Question: Who preceded Ali Daei as Saipa's coach? Passage:During one of Saipa's training camps in Ardabil, Karim's home city, he was taken on a training trial by then-coach Ali Daei and was accepted into the club's youth academy and reserves. In the 2007 season Saipa the Iranian reigning champions encountered problems in scoring after the departure of Mohsen Khalili and retirement of then-coach Ali Daei. After 12 weeks Ali Daei moved Ansarifard to the first team from the reserves and the young starlet answered the coach's faith with good games including the only goal against a strong Sepahan team. Ansarifard scored 13 goals during the 2009–2010 season. After strong performances, Karim became fast one of the best players of Saipa and targeted by European clubs such as Borussia Dortmund and Celtic F.C. later, FC Steaua București made a €200,000 bid for a half season loan. In May 2011, it was suggested that Everton are interested in signing Ansarifard. Despite major interest from European clubs, conscription problems made the prospect of Ansarifard moving to a foreign club unlikely. Ansarifard renewed his contract with Saipa for another two years on 14 July 2011. In the 2011–2012 Iranian Pro League season, Ansarifard scored 21 goals and made 5 assists for Saipa, becoming the league's top scorer.
