Tottenham have no European games to contend with this term after finishing eighth in the Premier League last season.
A strong start to the current campaign under Ange Postecoglou sees Spurs sitting pretty at the top of the Premier League table with a two-point advantage.
With their rivals involved in European competition in midweek, Spurs can move five points clear with victory over Crystal Palace on Friday.
“Honestly, it helps a lot. Physically, I remember last season was very hard playing three games a week,” Kulusevski said.
“You feel very tired in the warm-ups. Also, mentally not having to travel to Spain or Italy to play games helps. You are at home, with your family. You have a good rest mentally, so it is a huge thing that we have and we have to take advantage of that this year.
“You can feel the difference and hopefully you will see even more at the end of the season.
“It is early because we will see what happens. Everything can change every day so we don’t need to talk about (title), but we must live for the day with a smile, train hard and not forget who we are. We must try to get better every day.
“It is not important what people say. The important thing is to work hard, be humble, listen to the coach and keep the smiles on faces. Then at the end of the season we will see where we are.”
