Dier says the Special One can help them win their first trophy in 13 years after turning them into genuine title contenders.
Dier said: “That's something that's quite frustrating to be honest because I think, as I said before, there were seasons where we finished second in the league and people called it Spursy.
“We finished second. We just didn't manage to win it and people were calling that Spursy. I don't believe this team has had that tag for a long time.
“I don't think teams enjoy playing us. I think we're physical, I think we're aggressive, I think we're determined, we've got a good attitude and the manager has definitely brought an extra edge to that.
“He's more demanding in certain areas and ruthless with you individually and as a team so he's definitely increased that a bit as well."
