After pushing Leicester City in the title race for the majority of the season, Spurs dropped off dismally in the latter stages, and having been ahead of perennial rivals Arsenal, suffered a humiliating 5-1 defeat to Newcastle on the last day of the seaosn to allow the Gunners to leapfrog them into second on the log.
And Spurs coach Pochettino admits that defeat has left him with a sour taste in his mouth for the entire duration of his holidays.
"The feeling after Newcastle was horrible," Pochettino said via the Daily Mail.
"It is true that after a couple of months you move on, but it put me in a bad mood for the whole of the summer. It killed my holidays. Seriously. I went to Barcelona and the Bahamas with my family, but all the time I was in a bad mood.
"There was no time to assimilate the defeat at Newcastle because the season finished at the end of the game and I did not have the chance to share my feelings with my players the day after and kill them!
"Normally when you lose and you are upset with the players you have the opportunity to tell them how you feel on Monday morning when you meet them and have a big discussion and a big fight.
"But after the Newcastle game it was not possible because many of my players went off to the Euros. So I had to keep my bad feeling inside for the whole of the summer.
"Even when I was texting my players in France to wish them well I had to hide my real feelings about the Newcastle game."
Pochettino says he’s relishing the upcoming season, and can’t wait to mix it with the best in the Uefa Champions League.
"The Champions League demands more energy — physical and mental — and we need to be careful how we manage that and the expectation and the demands,’ he said.
"For me our challenge is to be consistent and consolidate our club in the top. And, is it possible to win the Premier League? Why not? We need to try again, no?"
