Tottenham are hoping to finish above Arsenal for the second straight season, having done so for the first time in 22 years last term.
Mauricio Pochettino’s side went into the international break level on 23 points with second-placed Manchester United, four clear of their sixth-placed opponents.
A draw at the Emirates Stadium would keep Arsenal at arm’s length but Dier said of an away fixture Spurs had only won once in their last 28 attempts: “The mentality going into it is to win. Simple really.”
Dier also revealed manager Pochettino had messaged him after he was named England captain for their first two World Cup warm-up matches against Germany and Brazil.
“I’ve had lots of nice messages,” he said. “The manager messaged me. For me, the most important thing is the people that are close to me: the manager, my family, my close friends, what they say, them messaging me. That's all I need, really.
“I spoke to the manager and he had some good advice for me, just to enjoy it. I tried to do that.”
