African champions Enyimba say they no longer have a job for their Australian coach Michael Urukalo after he failed to return from holiday.
Urukalo was appointed at the start of the season
Urukalo, who was appointed at the start of the season, took a two-week compassionate holiday in May but has since not returned to Nigeria from Sydney.
"We're not saying we've sacked him because he signed a one-year contract but we no longer have a job for him," club spokesman Tonnex Chukwu said on Thursday.
"We assume he's dumped us. He's not communicated with us since he left, his holiday has since expired and Stanley Eguma has taken the space Urukalo left," he added.
Urukalo was appointed after Enyimba sacked Kadiri Ikhana who led them last December to become the first Nigerian club to win the Champions League trophy in the 40-year history of the competition.
Chukwu also said the club had allowed goalkeeper Vincent Enyeama to travel to South Africa for a trial with Orlando Pirates but he was still expected to arrive Tunisia in time for their Champions League group phase match this weekend.
Enyimba, who top Group A, play fierce rivals Etoile du Sahel in Tunis on Saturday.
