The midfelder was superb in the 5-1 win.
Ramsey said: “I am delighted, it is one of the moments to remember.
"Full credit to the team, the game was won in the first-half and hopefully we can keep this focus and quality for the rest of the season."
He continued: "It was a great response, we needed that after the game at Swansea. We were at it from the off.
"Everyone was at it today, and when everyone's at it we are quality. Aubameyang and Mkhitaryan were brilliant today, you can see their link-up play.
"Our home record is fantastic, we need to replicate that on the road."
On debutant Pierre-Emerick Aubameyang, Ramsey added: "If that is not him at 100% then we have got a player on our hands. Plus Henrikh Mkhitaryan got a few assists. Hopefully there is a lot more to come and we can push on and finish the season strongly."
