Spurs' form in the Champions League may be suffering, with only one point gained from their opening three games in the group stage, but they have been promising in the Premier League, where they sat fifth and just two points off the top of the table going into this weekend's games.
In a lavish football universe where six-figure weekly wages have become the norm, Spurs are paying their star players wages that could be usurped by clubs like West Ham, Crystal Palace and Fulham and eventually, that prudence will catch up with them.
"It's a massive challenge for us", Pochettino said.
"When that happens, it is a solid team but to win games, especially important games like in the Champions League or Tottenham, you have to be so solid at the back and our conversion rate in front must be a little bit higher".
Pochettino said in a press conference when asked whether he is concerned about the size of his squad: "I don't believe that, we have a lot of players in the squad, young players that deserved to be involved".
Pochettino's side have dropped points in a 2-1 loss to Liverpool FC at Wembley at the start of September, while Spurs succumbed to a 3-1 defeat by Watford at Vicarage Road. Disappointed because we are still waiting for the new stadium when the expectation was to be there from the beginning.
"It's odd because it's my worst feeling here in four-and-a-half years", Pochettino, who has taken Tottenham to third, second and third-placed finishes in the last three seasons, told reporters at the club's swish training ground.
Mauricio Pochettino says this season has seen him endure his "worst feeling" as Tottenham's manager despite guiding them to their best ever Premier League start. I'm feeling confident and I'm looking forward.

Valverde not only has to find a suitable replacement but also has to ensure Messi's absence doesn't damage his side's confidence. Radja Nainggolan has missed out on a place in Inter's squad for the Champions League fixture against Barcelona due to injury.
"I am completely different now", he told Sky Sports.
Tottenham conceded seven goals against Pep Guardiola's side last season in their two meetings and will be up against opponents who have spent around £360m more on transfers and three times as much on wages since 2015.
"These are important. I don't know what's happened in the past but it's true that the strong teams are making a lot of points, they are not dropping points easily".
"Today, we spend a lot of energy in many things". One is to win games, but the club need to be all focused in trying to win titles.
"I think the most important thing ahead of the game is how we feel, how we prepare for the game".
Tottenham face a daunting test against Manchester City, who will be eager to return to the top of the Premier League table, but Redknapp believes Pep Guardiola's side will find this season far tougher than previous year.
"No, it wasn't the plan for us to be playing this game at Wembley but that's the reality now".
