Sheffield Wednesday midfielder Kieran Lee is interesting Sunderland.
But the player's boss at Hillsborough Carlos Carvalhal says he is not worried about in-form Lee being linked with a switch away from the Championship outfit.
"I don't know nothing about it, it's news to me," said the Owls boss.
"I am not concerned about nothing.
"I am happy when other clubs are interested in my players, especially big clubs, or the clubs in the Premier, but nothing more than this.
"Something that I know is that Kieran Lee likes working with us and he likes being at Sheffield Wednesday."
