Tottenham target Stanislav Lobotka has a buyout clause in his Celta Vigo contract.
Pochettino, yet to make a signing with just four days of the transfer window remaining, has been assessing his options with Mousa Dembele keen to leave before Thursday's deadline.
Lobotka, 23, is a Slovakia international who only signed a new deal in February which runs until June 2023.
However, he has a £31m release clause in his contract, however, and his club revealed last month that he wants to move on.
Napoli are also interested in his services.
