Bio Paulin opened the scoring for Persipura in the 19th minute before Ian Kabes made it 2-0 in the 41st.
Despite having a comfortable 2-0 lead at half-time, Persipura continued to attack and were rewarded with three goals in five minutes as captain Boaz Solossa struck with a quick double and Kabes found the back of the net once again.
Substitute Gerald Pangkali slotted the ball into the back of the net in the 88th minute to hand his side a convincing 6-0 win.
“My players put on a good performance today, keeping good possession of the ball and putting our opponents under a lot of pressure when they had it," Lessa told the official AFC site. "We’re pleased to get the points that ensure we remain the group leaders and I hope in our last group tie against Bengaluru we are able to secure the point we need to claim the group.”
Having lost all five of their games thus far and been eliminated as well, Warriors FC head coach Alex Weaver is hoping that his side can finish their AFC Cup campaign with a consolation win against Maziya Sports & Recreation on May 12.
"The first half we played quite well, but in the second half we had a difficult time in implementing our strategy on the game," he added. "The Persipura players put us under a lot of tight pressure and as a result our players lost focus and concentration."
