Tottenham have signed a contract with goalkeeper Antonin Kinski from Slavia Prague.
The 21-year-old will fly to London on Saturday and have a medical on Saturday evening.
Spurs will pay £12.5m for Kinski, who is a Czech Republic Under-21 international.
Spurs have serious problems in goal, with first-choice Guglielmo Vicario injured and Fraser Forster among those who have picked up an infection in the past week.
Kinsky has kept 12 clean sheets in the Czech First League in 19 league appearances for leaders Slavia Prague this season.
What are Spurs' plans for the January transfer window?
Tottenham are looking to strengthen their squad this January, looking at different positions due to injuries to key players and a drop in form as a result.
Although he has done well in the circumstances, Archie Gray's playing at centre-back has not been ideal, so this is one area where the club are looking to add depth, as well as in the forward and central midfield positions.
They wanted to Conor Gallagheror someone like him, in the summer, while Timo Werner was brought in on loan in wing positions, not permanently, and injuries on Richarlison and Wilson Odobert they left them without options.
Spurs want those players back and competing for a place, especially Richarlison, who has no desire to go anywhere in January alone. Sky Sports News he understands.
South Korean winger Min-Hyeok Jang18, officially joins the club on January 1 following his time at Gangwon FC. He has already arrived in England and has begun to settle into his new surroundings, but is a developing player for the future.
