In the 79th minute, the winger from Casabia did a good job.
A cross from the flank caused an own goal by the Lisbon's center-back.
It was 3-1, as Casabia clawed back a goal.
But just nine minutes later, Ronaldo, who knew he couldn't rely on Deng Kai, still managed to score with his immense individual talent, pulling off a solo run.
He netted his thirteenth goal, maintaining his position on the top scorers' list.
In the end, Lisbon won a resounding 4-1 victory over their opponents, achieving their first back-to-back league wins.
This match made people realize that Lisbon's U15's victory in the previous round was not just a fluke.
Some believed that Deng Kai was the reason for Lisbon's radically improved strength.
But many felt it was just the norm for young players, sometimes underwhelming and other times outstanding, nothing special.
For Deng Kai, this game furthered his understanding of his skills' effects.
