Pule, who has played every game for Bucs this season since joining from Bidvest Wits, scored his second goal for the club in a 3-1 win over SuperSport United at Orlando Stadium on Saturday.
The 26-year-old is also enjoying international recognition, having made his Bafana Bafana debut in the goalless draw with Libya in a 2019 AFCON qualifier in Durban 10 days ago.
“All the players that came, they really added value to the team,” Sredojevic said after a second successive win for his charges on the weekend.
“However, we could not immediately put all of them in. Now all the new players, all of us we know each other.
"He [Pule] has really fitted well into the system. He is doing very well and I believe that calling him into the national team is a real merit, he deserves it.
“In the same moment, I want this to be an injection of motivation because all our players, they have unbelievable room for improvement and space for development.
“And that’s what motivates us as a technical team because we believe that our players are working very hard, day by day to be better human beings, to be better players and this is what is the driving force.”
Pirates, in third place on the table with 10 points from six matches, next entertain Cape Town City on Wednesday.
