The 32 year old is set to start against West Ham in the Carabao Cup clash at Wembley.
The Spurs boss said: "It is important to analyse; we have Harry Kane in the last few years, and it is not easy to find the profile that can compete with him.
"And it is not easy on the market to find a player that wants to come and compete with Harry. The world recognises him as one of the best strikers in the world. That is why Llorente is the perfect fit for us."
