The 27-year-old left-back has been linked with Manchester United.
"I don't think about it," Conceicao said about a possible exit for Telles after a win over Braga.
"The market is not about me. I am not a manager, I am a coach and I have to train the players I have.
"Obviously I would like to count on everyone and if someone else came in, I would not be upset at all."
On Telles attitude, Conceicao added: "I must praise and emphasise Alex's professionalism.
"It is not easy with all this news to play the game he played today.
"I know the character and personality of the players and I know that until the last day, be it tomorrow or 10 years from now, they will do their best."
