Ghana striker Asamoah Gyan's availability is a massive boost ahead of Tuesday's Asian Champions League meeting with Al Rayyan in Qatar.
The Black Stars captain is set to return to action for the club after suffering a thigh injury while playing for his country in last month's World Cup qualifier against Sudan.
He missed two matches for the club since suffering the injury but has recovered and travelled to Qatar with the side for the game.
There is optimism in the Al Ain camp that Gyan, the Ghana captain and the club's top scorer, will return from injury to play the game, though he will likely start on the bench.
Al Ain coach Cosmin Olaroiu has had little time to work with his players since the match in Dubai against Ahli on Saturday. His team beat Rayyan 2-1 at home a week ago.
"Our timetable is so tight in the last two weeks we barely had time to prepare," he said.
"This meeting with Rayyan for the second time in a week will be harder than the first leg match, but we will do our best till the end."
A win on Tuesday night at the Ahmed bin Ali stadium in the city of Al Rayyan would be Al Ain's third in four games and give them a healthy chance of making the knock-out round
Al Ain are second in the group on six points, one behind Esteghlal of Iran, who host third-placed Al Hilal of Saudi Arabia also on Tuesday.
