Eymael will make the call after his team plays a friendly with SuperSport United on Saturday.
"You know Twala is here, Makudubela is here, we have the winger of Arrows Yusuf Jappie, and we still have Saal," Eymael tells KickOff.com.
"We'll decide about them after Saturday's game. We are playing a friendly against SuperSport. And I'm sure that we will sign two of these four."
Eymael also took the opportunity to reveal that defender Thamsanqa Teyise has finally parted ways with the club after his contract was not renewed. The Eastern Cape-born player competed in 17 matches in all competitions last season, scoring one goal.
"Now you can say also that Teyise has been released. So he is free now, he can sign where he wants to."
