Guernsey FC boss Tony Vance said 16-year-old Paris Pereira would get a huge confidence boost from scoring the winning goal for his side on Saturday.
Pereira came off the bench to grab an 86th-minute winner in the Green Lions' 2-1 win over Faversham Town after Marc McGrath had put them ahead.
"It was fantastic for him to get the winner," he told BBC Guernsey.
"It was his first goal for us. He's only a young lad - that will do him the world of good for his confidence."
The win continued Guernsey's outstanding away record this season, with Vance's men still to lose on their travels, and moved them up to fifth place in the table.
"It was a very hard-earned victory," said Vance. "It wasn't the prettiest game of football and they had a tremendous threat with a long throw, which was causing us all kinds of problems.
"But as long as we could cope with that then we had the firepower to score goals.
"This is what these boys are about. They play for the badge and for their pride in their island and we had to dig in and it was a massive three points."
