Hibs lost their season opener at Kilmarnock but Paatelainen was content with the level of performance.
"We created lots of chances and we paid the price for not taking them," he added. "But the goals will come.
"Maybe we need a lucky one to go in off someone's knee.
"We are fighting to get it right and the players are focus and fully committed."
Pinau is the fifth new arrival at Easter Road this summer and Paatelainen, who is hoping to offload a few players before the end of August, may yet move for more recruits.
"We are still looking at one or two areas and, if the right opportunities arise, we will act," he said.
