Eric Lichaj still feels he has much to improve despite making his full Premier League debut in Aston Villa's 2-1 win over West Bromwich Albion.
The USA international got his first 90-minute dose of action in the top flight and turned out a performance that drew praise from his manager Gerard Houllier.
Lichaj came in for the injured Luke Young and did well against West Brom's Jerome Thomas but the 22-year-old wants to continue his rise from the Villa reserves.
He told Sky Sports HD: "There are a lot of things I can improve upon. I got skinned by Thomas a couple of times and I got the best of him a couple of times. I guess that's how it goes but I need to improve my defending.
"If I was in the stands then I might have been laughing because I was left on my behind but we won and that's all that matters in the end."
Lichaj felt Villa were deserving winners on Saturday courtesy of goals from Stewart Downing and Emile Heskey.
He said: "We fought very hard for the whole game and we took our chances when we needed to. They are a very good side and they like to play football but we deserved it in the end.
Marc Albrighton played a role in both goals and Lichaj was glad to have the young winger playing in front of him.
He added: "He's done very well. He was injured but he's back and it's good to have him back.
"When I played in the reserves he was always in front of me and it's good to have him in front of me because I know what he does."
