ABU DHABI: It was all about the second half. Kwesi Appiah went into the dressing room with the players and returned with no changes in personnel. But they came with a change of mind.Ghana scored four goals in the second to come back from two goals down - a rare feat indeed - to beat Tunisia 4-2 at the Sheikh Zayed Sports City Stadium in Abu Dhabi.Issam Jemaa had gotten two goals, before Appiah’s tactical changes started the turnaround. John Boye produced a photocopy of Emmanuel Agyemang-Badu’s opener against Egypt days ago when he powered a Mubarak Wakaso freekick past Aymen Mathlouthi.Then Wakaso himself, after Christian Atsu was fouled, blasted the ball into the top corner of the net from the penalty spot. Having come off the bench, Asamoah Gyan got his name on the score sheet. And then Albert Adomah, also a sub, finished the comeback with a shot from close range.The final warmup for the Stars started with Kwesi Appiah opting to go Solomon Asante and again, Kwadwo Asamoah at left back. John Boye started in place of Isaac Vorsah who had pulled a muscle shortly before kickoff.The game was played in an empty stadium because organisers said there was a security precaution.
