Spurs boss Mauricio Pochettino believes his Tottenham side are better for last year’s experience, when their title challenge faded leaving them to finish third in the Premier League.
Tottenham beat Bournemouth 4-0 on Saturday to get within four points of Chelsea and keep the pressure on the league leaders as they head to Old Trafford on Sunday.
"I think we learned a lot," the Spurs boss said.
"That was a very bad period at the end of last season. We expended a lot energy fighting against Leicester, but against West Brom, against Chelsea, against the media. We fought against everyone. But now we are focusing on fighting our opponents when we play,” he added.
"Then we spend time and energy on preparing ourselves to compete in the best way. We have improved a lot, from the beginning of the season that was our chance to improve our mentality, our belief and I think you can see the group and the team have improved."
The Argentine also said that goal difference will be important in the title run-in this season.
Spurs now have the best goal difference in the league.
"It's so important. The only way to build that winning mentality is to always play in the same tempo, with the same focus during the 90 minutes,” he said.
"3-0, 4-0, it's important to keep possession, to score goals and that is the mentality we are building. Four points is still a lot. If they (Chelsea) drop points tomorrow that will be fantastic. But they are still the favourites to win the Premier League.
"We are fighting for ourselves, for the second consecutive season we are there, and I think that is a great credit for players and the club."
