Mauricio Pochettino says Tottenham will have to be “clever” when signing new players and admits they cannot compete with the top Premier League sides.
Spurs' most recent acquisitions include Moussa Sissoko, Vincent Janssen, Victor Wanyama and Georges-Kevin Nkoudou, who all arrived for big money.
But as the north London side turns its attentions to building a new stadium, Pochettino has revealed he will have to invest wisely if he is to further strengthen his squad.
Speaking to prior to facing Hull at the soon to be demolished White Hart Lane on Wednesday night, he said: "For us, it is very difficult to sign players like our opponents.
"When you compare Tottenham with Liverpool, Chelsea, [Manchester] City, [Manchester] United and Arsenal, in this moment it is very difficult to compete with them.
"The challenge is to be clever and to take risks – and as we know, when you take risks in football, sometimes you win and sometimes you lose."
"No friends on the pitch!"

Pochettino, though, knows the new stadium will be a massive boost for Spurs and feel they could become one of the top teams in the world.
He added: "It's not about money, it's how you invest the money. Now the market is crazy. You can see how the value of players has increased. It's true you need to be clever. You need to be imaginative and creative. And try to fight for good players at a very good price.
"When you're building a stadium like we're building you are not only focused to improve the team.
"You need to be focused on improving the team but at the same time you're spending money to create a massive stadium which will be one of the best stadiums in Europe. We needed that.
"With the new stadium, Tottenham will be one of the best teams in the world, for sure. But now we need to be creative and sometimes take a risk and when you take a risk sometimes you win and sometimes you don't."
