Both players were ignored by England coach Roy Hodgson for the looming friendly against Denmark.
“They’ve just got to stick at it, stay with it and, as I’ve said before, there’s always a surprise,” said Bruce.

“I’m sure they’re in and around. I can only speak based on what I see, and Roy’s got his job to do.

“For Curtis and Tom to be even linked with it, they’ve got to stick with it and keep performing, then who knows?”
