Llorente is on a season-long loan at Alaves, but has been linked with an early return.
"Marcos Llorente is on loan for the season. There is no return clause," said De Troconiz.
"What is included in the contract is a clause that Real Madrid usually imposes on loans and means that the player cannot play against them.
'Each team imposes its conditions, but I insist that he's on loan for the season."
