"Ngog showed his quality and I always say the same: our scout department is working really hard to find young players at a good price. Hopefully it will be the first of many goals," said the Reds boss.
"We showed from the start that we wanted to impress and win against a good team.
"Both teams worked hard in the first half but we had good possession and played with a high tempo. We scored one and, though we had some problems towards the end, we controlled the first half.
"The second half was more open, so it was easier for us to move the ball and pass it.
"Robbie has settled in well. He is a clever player and has been working very hard. He is happy here and hopefully we will see a lot of good movement and goals from him.
"We have some leaders in the team and little by little each one will have his own position."
