Edgar was named as a first-team substitute for the first time against Bolton Wanderers in the Carling Cup last week. He believed it was a step forward that should put him in good stead for first-team action on the south coast.
"It was great experience," Edgar told whufc.com. "I didn't get on but I was looking up at the players like Zavon Hines and I will learn a lot from that.
"It was a great atmosphere. We didn't win but it was a good experience and I would like a lot more of that. I just want to keep working hard and see what happens."
