The Sky Blues secured a 2-0 away win over Gladbach in the first leg of their Champions League last-16 tie.
"It was a good game for us, a good win," Silva told BT Sport. "In this competition you can make a mistake and you're out. We tried to play simple football and not make mistakes.
"It's not finished yet but it's a good win.
"Usually I'm not [deadly with his head]. I try to practice a lot. I think tonight I was lucky Joao [Cancelo] gave me a great ball. I'm happy to score and help the team.
"He's an amazing player. I played with him seven years at Benfica, we're the same generation. We have a good connection. He knows my timing and I know how good he is on these balls.
"We need to keep going because we're only halfway through.
"We have a map, a way of playing. Players get injured or cannot play and our style doesn't change."
