Manchester United broke the world transfer record earlier this week with the £89m acquisition of Paul Pogba from Juventus, taking their total spend for the summer past the £140m mark.
Manchester City have also joined their neighbours in spending big this summer, laying out close to £150m on eight new recruits.
Spurs, in comparison to the Manchester clubs, have been relatively quiet in the transfer market, signing just two players ahead of the 2016/17 season – midfielder Victor Wanyama and forward Vincent Janssen for a combined £28m.
But Pochettino is convinced the big spending from rival clubs is just a sign of their unhappiness of the standard of their current crop of players.
“That shows when you spend a lot of money it is because you are not happy with your squad or your players and you are desperate to improve your squad,” he said.
“I am very happy with my players, I think it is very difficult to find better players than we have.”
Despite this, Pochettino admitted his openness to signing another two players before the close of the summer transfer window, but insisted any potential new recruits would need to improve the existing squad.
He added: “We are open to adding one or two players or maybe no one. But if we have the possibility to sign a player that can improve us, we are very open.”
