Semenyo now has five goals in eight appearances since his January move from Bournemouth.
Speaking after Wednesday night's 3-0 win, the Ghana attacker said: “(There’s) no secrets! It’s just being part of a great team, a great environment, the coach has been great and they’ve made it easy for me to settle. It’s all a fairytale right now.
“(It was) very important (to win). That was the message from when the game was done against Liverpool. Just backing up what we did on the weekend, it was a tough graft and we got the three points, today we did the same thing. I’m happy."
City are now three points behind Prem leaders Arsenal and Semenyo also said: “It’s new to me. I’m enjoying it. But obviously It comes with a lot of pressure and demands. We have the team to do it. We just need to keep going.
“Just going to sit tight and watch the game tomorrow and hopefully it goes our way so let’s see.”
