Ruddy made England's Euros squad only to be ruled out on the eve of the tournament after breaking a finger.
"It's always at the back of your mind that you might get an England chance again, " said Ruddy.
"It was a blow to miss out and it was a strange kind of injury. I went to gather a ball during my second training session and it dipped and caught the end of my finger.
"But I'm fit and I would love to be part of the England squad again and, hopefully, that will happen."
