Even though their match against Balestier Khalsa FC was delayed by a thunderstorm, Kitchee still went on to win 2-1.
Kitchee forward Juan Belencoso was on song right from the beginning as he opened the scoring in the 14th minute.
Balestier levelled things up in the 33rd minute when midfielder Muhammad Fadhil found the back of the net with an incredible long-range effort.
However it was the Hong Kong-based side who triumphed in the end as Belencoso scored his second goal of the match in the 61st minute.
"We played really well," Molina told the South China Morning Post. "We created a lot of chances but only scored twice.
"Yet, the most important thing was to win the match and we did that.
"It is good to come away having booked out berth in the next stage. We have been playing some fantastic football in the past month, winning a lot of matches and titles. This is one more good result and I hope we can continue this momentum."
Kitchee had numerous chances to increase their advantage over Balestier, but Belencoso missed two golden opportunities to do so.
Despite this, Molina pointed out that the 33-year-old Spaniard "played well and did his job".
"He missed a couple but he also scored both our goals," Molina added. "He is a striker and everyone expects him to score all the time. He played well and did his job."
