The 21-year-old made his debut in Tuesday's win over Northern Ireland and he has now targeted a role in Stuart Pearce's squad.
"I just wanted to make an impression and put a thought in the manager's mind come the summer. I am a bit unfit but I showed glimpses of what I can do. Hopefully if I am given a chance I can impress further," he told reporters.
Townsend has made four appearances for Spurs this season.
