Wigan Athletic striker Amr Zaki has apologised for failing to return from international duty on time, the Premier League club said on Saturday. The Egyptian forward, who has scored 10 goals for Wigan this season, failed to return following a match against Zambia on March 29 after sustaining a hamstring injury. "He (Zaki) said the reason for his behaviour was personal but he understands he has done wrong and will accept the fine the club has imposed," chief executive Brenda Spencer said in a statement on the club website. "He also wants to apologise to the supporters who have been so good to him since his arrival in England." Last week, manager Steve Bruce branded Zaki 'unprofessional', adding that it was the fourth time he had not reported back on time from international duty since joining on loan from Egyptian side El Zamalek. Despite making a good impression in the Premier League this season, Zaki has not scored since December and his behaviour could jeopardise a permanent transfer to England. "Steve (Bruce) has told him that the door is not closed for him but he has a lot to do to earn a place back in the team. That is before we discuss anything more long term," Spencer added. Zaki is not involved in Saturday's match at home to Arsenal.
