Former England wicketkeeper Matt Prior says Jamie Smith needs to relish being the "heartbeat" of England's team and be up for "the fight" of trying to help the tourists recover from 2-0 down in the Ashes series.

Smith has struggled in recent matches, failing to pass 33 in his past eight Test innings, while mistakes have crept in behind the stumps with the Surrey man dropping Australia's Travis Head in the second Test in Brisbane.

"The keeper's role has always been the heartbeat of that group on the field," Prior, who won three Ashes series with England in a 79-Test career, told the BBC's Stumped podcast.
