The former Manchester United midfielder struck from the halfway line for the first senior goal of his career.
Gomes said, "My father always says to look at the goalkeeper and that's what I did. He scored a lot of goals.
"We should have won this game. We have the best opportunities, but the most important thing is to win the game. We lack the victory, but we will come back stronger."
Gomes' father won the U20 World Cup with Portugal.
