A second-place finish in the Absa Premiership would book the club a spot in the preliminary stages of the showpiece but they currently reside in third, a point behind Mamelodi Sundowns.
Ahead of the final weekend of action Walters delivered a well reasoned analysis of his side's chances of clinching the coveted second position.
“That is what is playing on our minds [competing in the Champions League], but at the end of the day it’s not in our control,” Walters tells KickOff.com.
“The only thing that’s in our control is to try to get three points [against Polokwane City] and hope that Sundowns lose, but if you look at Highlands [Park] and the way they played the whole season it’s looking very unlikely that Sundowns will lose.
“And Sundowns also themselves they’ll be a little bit motivated because they want to play in the Champions League next year.
The Citizens are already guaranteed a spot in the CAF Confederation Cup next season by virtue of finishing at least third - their position cannot be usurped by any clubs below them.
Walters adds that team has been preparing well for their clash against Polokwane City, which will be played at Old Peter Mokaba Stadium on Saturday at 3pm.
“The preparations [for the Polokwane game] are going well, but it’s a bit of a tricky situation because we've already confirmed third place; and it’s just a mental thing to try and motivate ourselves… knowing that it’s the last week of the season for us," he said.
“So, for now it’s just to keep the guys motivated and insuring that we can stick to our game-plan going to the game against Polokwane.”
