The north London side showed resilience to come from 1-0 down and beat Swansea City 2-1 on Sunday courtesy of goals from Nacer Chadli and Danny Rose.
This team has a level of maturity that surpasses that of previous squads
Spurs have slipped away in the race to secure a top-four finish in recent seasons under Andre Villas-Boas and Pochettino.
Tottenham face Arsenal in the north London derby on Saturday and the Gunners have also developed a reputation for choking in the final months of the season.
However, former Spurs midfielder Jenas believes Pochettino’s current crop have shown a shift in mentality so far this term.
“The manager will no doubt be aware that it was exactly this time last year when Tottenham’s season began to unravel. They were beaten by Chelsea in the League Cup final and then fell away in the league.
“That’s why he would have been so encouraged to see them bounce back from last week’s FA Cup defeat to Crystal Palace by negotiating a tricky Europa League tie against Fiorentina and then coming from behind to beat Swansea.
“It’s further evidence of the huge shift in mentality from last season.
“Tottenham fans will always fear the worst, but I think they can sit comfortably knowing this team has a level of maturity that surpasses that of previous squads.”
Tottenham have won their last six Premier League games after victories over Sunderland, Norwich City, Watford, Crystal Palace, Manchester City and Swansea.
Pochettino’s side make the short trip to Slaven Bilic’s West Ham at Upton Park in the Premier League on Wednesday night.
Spurs host bitter north London rivals Arsenal in their next home game in the English top flight on Saturday afternoon.
