The two sides will come up against each other in Absa Premiership action tomorrow evening at the Lucas Moripe Stadium, with kick-off at 19h30.
However, Eymael is still unable to take proper charge of Celtic due to the ongoing case involving his former employers Polokwane City.
"There's a good relationship between me and Pitso [Mosimane],” Eymael tells snl24.com/kickoff. "But, unfortunately, I won't be on the bench.
"We respect Sundowns, they are the best team in Africa. They have the best coach in Africa and the best players that play good football. So we have to be very cautious on Wednesday."
The Belgian coach says most people are making a huge mistake by thinking Sundowns are wounded, after seeing the Chloorkop giants fall to a 2-1 loss to Kaizer Chiefs last weekend after Bangaly Soumahoro’s decisive own-goal.
"You saw on the weekend that they [Sundowns] were beaten because of their own mistakes. If it wasn't for those mistakes I'm not sure if they were going to lose that game,” the coach says.
This website also asked Eymael about the future of Lyle Lakay, who is rumoured to have attracted interest from Bidvest Wits and Cape Town City.
"Lakay is a very good player,” says Eymael. "On Sunday [against Polokwane City] he promised me he was going to score and he did score. But I don't know anything about his contract situation."
