Musonda is set to receive the PSL Golden Boot award after scoring 16 goals, while Sirino played an important role in helping Sundowns defend the league title.
"But I guess this shows you the standard of the PSL, how tough it is and I hope people understand this,” he continued.
Zambian marksman Musonda, who is a former Orlando Pirates striker, scored crucial goals which helped Leopards survive relegation from the top flight league.
On the other hand, Uruguayan playmaker Sirino contributed assists and goals as Sundowns won a record-extending ninth PSL title.
“I had selected three, I wanted to bring in a goalkeeper but I thought Musonda, I was trying to invite strikers to say he has been doing well and scoring and he is also an inspiration to young players that you can also go for it," he added.
The former Kaizer Chiefs coach went on to disclose that he had Zwane, Lorch and Musonda in his ranking.
"In my ranking I had Themba Zwane, Thembinkosi Lorch and Musonda from Black Leopards," he concluded.
The 2018/19 PSL Awards ceremony is set to be held Sunday, May 19.
