Tunisia midfielder Youssef Msakni has described their quarter-final opponents Ghana as the most formidable team in the tournament.
Msakni, one of seven Esperance players in the Tunisia set-up, says they must overwork themselves to oust Ghana.
"Don't joke with Ghana. They are the team with the best compact play in the tournament. They are very focused and precise in front of goal. That is what makes Ghana very dangerous," Msakni told Goal.com on Thursday.
"Don't let the Black Stars score against you first or you are dead. They know very well how to conserve their spoils.
"And again, they've got strength and stamina. It’s very hard to mark a left-footer in football and most of the Ghanaian players are left-footed. You pounce on Andre Ayew, you cause your side a fatal free kick," he added.
Playing Ghana in the quarter-finals will entail strategy and inspiration, but Msakni said it would be up to the coach to handle the situation.
"I don’t know what will happen or how we’ll play against Ghana. Our coach will try to draw up something. All I can say is that playing Ghana that day will be like playing the final of the 2012 AFCON.'
The 21-year-old has scored two of the Eagles of Carthage's four goals in the competition so far.
