The midfielder is hoping they have ridden themselves of the soft tag that has plagued the side for years.
The Argentine boss has come in for widespread praise this season, with his side currently in a fine run of form.
They are unbeaten since the opening day loss to Manchester United, with Sunday’s win over rivals West Ham taking them within two points of the top four.
Their manager was a lively character on the Upton Park touchline in that game, with him remonstrating with his side despite them cruising to the 4-1 win.
And Dier says that desire to ensure they don’t become complacent in games is what makes him perfect for their young team.
“He doesn’t let us rest on our laurels,” the Mirror reports him saying.
"We are a young team and need a manager who tells us if we are getting complacent or making too many mistakes. He wants us to play at 100 per cent no matter what the score is or what time of the game it is.”
The midfielder is also hoping that they have finally ridden themselves of the soft tag that has often been stuck on them as a side.
Spurs have been known for playing good football for a number of years, but have been criticised for having a soft centre that ultimately sees them crumble at key stages.
This season has seen them drop that somewhat, with the defence having been impressive and Dier impressing in a new defensive midfield role.
And Dier says they have proven a lot of people wrong with their aggressive nature this season.
“Hopefully we have got rid of that ‘soft’ label because it is not a nice label to have,” he added.
“I think we have proved a lot of people wrong. We have played some very aggressive football, we get stuck in, we get about, and I think we are a team most others don’t want to play against.”
