Early career Kruja signed a three-year contract extension in January 2014 with a €100,000 release clause. In January 2015 he joined
Saudi Professional League side
Hajer Club for a transfer fee of $70,000, where he signed a three-year contract worth $300,000. He was loaned back to the
Albanian Superliga as he signed an 18-month loan deal with
Flamurtari Vlorë shortly after signing for Hajer Club. However, Kruja's loan at Flamurtari was cut short and he subsequently went to join another Superliga club in
Laçi on a season-long loan deal. ==References==
