Sundowns sealed their fifth consecutive league title after a 0-0 draw against Cape Town City at Loftus Versveld Stadium on Wednesday.
The point sees the Brazilians attain an unassailable lead with still four matches to play in the 2021/22 campaign.
Speaking after the final whistle, Mokwena called for an intensified title fight that could better equip Sundowns to compete on the continent.
"To not have that type of situation [a farmers league] you need strong rivals," Mokwena said post-match.
"Maybe the reality is that if you look at the stories such as Bayern for example and how they win their titles. The same with PSG, then they go into that sort of Champions League level and then maybe the stimulation is not there.
"Of course, I think every time Bayern have done well [in the Champions League] is when they have had very strong rivals in the domestic league.
"That responsibility to make sure that there are stronger rivals in the league, unfortunately, is not our responsibility.
"We have the potential to have strong rivals with regards to some of the teams and it's a difficult responsibility and I'm glad it's not my responsibility."
