The visitors probed late on to find a leveler, although it was Spurs who went closest in the final moments but Danny Rose could only fire straight at Dubravka, but it didn't matter as Kane's goal was enough to guarantee Tottenham Champions League football at their new stadium for next season.
"If you analyse all the context, I think it's an awesome season", Pochettino said.
"But I understand people want more".
It is a must-win match at Wembley Stadium for Spurs as they look to finish in the top-four and hence, qualify for the UEFA Champions League, but they will have to make do without the services of Eric Dier for the tie with the Magpies. We need patience, we need to work hard. It's in our hands and we need to die to achieve that. Sometimes you need to be focused on maybe doing some different movements.
"For me, it is like a marathon to create a team capable to win. In November, I remember the media said [to me]: 'Why do you rotate?' Now, maybe, some players that didn't play so much in the first six months of the season are going to be decisive".
"If we can not then we can not, that is different, and we need to analyse why".
"Of course it's never enough in football and I always told the players, after working hard for two hours in a training session 'yes well done but it's not enough, it's not enough".
Sonam Kapoor's wedding reception: All the Bollywood guests you missed
However, the best wish came from dulhan ka bhai Harshvardhan Kapoor who shared a special message for brother-in-law Anand Ahuja. A bigger guest list was sent out for the reception since the wedding ceremony was mainly attended by close friends and family.
Spurs finished as runners-up behind Chelsea last season and challenged Leicester City for the title in 2015-16 but Pochettino said finishing third or fourth would still represent progress for the club, given they have spent the entire season playing at a temporary home.
"For me, (there has been) unbelievable progression", Pochettino told reporters on Tuesday.
Away from home Newcastle have only won four league games this season as well, losing ten of their 18 games and only scoring 18 times.
Newcastle arrive in the capital with very little left to play for as they sit comfortably in mid-table on 41 points having already secured their top flight status for another season.
"After, you move to Wembley".
"The money is the second thing, but the first is that to play in the Champions League is the dream of everyone".
In a frustrating midweek fixture, Pochettino was forced into a number of changes due to injury and illness, but the inclusion of Moussa Sissoko and Victor Wanyama in the deep-lying midfield positions had a serious impact on the way the side played. We know where we want to be.
"Yes, we hope he will be available [against Leicester] for the weekend".
