Spurs currently sit sixth on the Premier League table after narrowly missing the Champions League last season and right-back Walker feels that with the quality in the squad and the knowledge of their boss, the North Londoners can find themselves back in Europe's premier club competition next term.
"With the players we have and the players we brought in, I am more than confident (we can finish in the top four)," the England international said.
"We just need to keep listening to the gaffer and his tactics.
"If we do that then I most definitely think that we will get the results we need.
"It was disappointing how it went last year but that's just the way it goes."
