Alaves president Josean Querejeta is unhappy over reports Theo Hernandez is set to join Real Madrid.
Theo is on-loan at Alaves from Atletico Madrid.
"We didn't know anything, we had no idea," Querejeta told El Transistor on Onda Cero. "We learned through the press that he has passed a medical [with Madrid].
"I have not spoken with [Theo]. We have a good relationship with Madrid, but it seems strange to us that he's passed a medical. It's surprised us that no-one has told us anything about a player that's at our club."
Barcelona had also been interested in Theo and they will play Alaves in the Copa del Rey final on May 27, an important game which Querejeta hopes won't be affected by this transfer saga.
"Everything we know is through rumours," he continued. "No-one, not Barça, not Madrid, not Atletico has spoken with us about this.
"It doesn't help keep things calm and balanced ahead of such an important game on May 27, when we play in the cup final."
