Tomkins appeared in the Barclays Premier League meeting with Aston Villa and Carling Cup second-round victory over Oxford United, but has found first-team chances harder to come by in recent weeks.
He told whufc.com: "It's important to get match-practice in - that's important. I've known Alex (Dyer) for a long time and he's a good man, and he has got a good team spirit in the reserves, which is good.
"I really want to play. I'll keep working hard and trying to impress in training, as that's all I can do. If I do play well for the reserves, hopefully the feedback will get back to the manager and, you never, know, I might get to play. That's all that I want to do - to play."
