The former Burnley man has been kept out of the team by Walker's impressive displays.
Many observers thought the arrival of Ben Davies last summer would spell trouble for Rose’s prospects, but the 25-year old reacted well and emerged as first-choice - becoming one of Spurs’ best players in the process.
Kieran Trippier’s signing this summer has given Walker real competition for the first time since Vedran Corluka was around, and the pacey right-back has reacted similarly well.
The England international has been a vital component of a Spurs defence that is currently the joint best in the Premier League – having conceded seven in nine games – and he is in no mood to give up his place.
“You have to back yourself,” he said, in an interview with talkSPORT.
“Last season, when Ben Davies came in, me and Dan [Danny Rose] were wondering whether he’d play - In the end I’d say Danny was our standout player.
“Harry Kane got a lot of plaudits for the goals he scored, but Danny’s work ethic was second to none and I’ve tried to do the same as him this season.
“Kieran is a very good player, but you have to believe you’re better. I didn’t have the best season last year, so I had a lot to prove – not just to myself, but to the fans. And my dad, who’s my worst critic,” he added.
Trippier has so far been limited to cup outings and barring injury or a drastic drop in form, his prospects of breaking into Mauricio Pochettino’s main team are slim at present.
