He said: "I had a really good start and to score on my debut against Chelsea - and at home - was fantastic.
"I came back in and had one or two below-par games. But overall in the last few games I think I've done well."
Knight revealed he was Villa mad as a kid, adding: "I used to stand on the terraces and I remember beating Inter Milan down at Villa Park on penalties.
"Phil King got the vital penalty and he was a hero for a long time after that. It was massive to knock out Milan, who were one of the biggest clubs around.
"I remember at the final whistle running on the pitch when we won but don't tell the chairman that! I would have got banned if I did that today.
"I dreamed of playing in games like that especially for Aston Villa. I've always wanted to play for Aston Villa and to achieve the dream is a great feeling. To do it Europe would be something special."
