Mourinho is a keen admirer of the 20-year-old, who has scored three goals in four games for the Portuguese champions since joining from Bahia in July.
Speaking with TVI24, Mourinho said: "I think Benfica hired well. They say Talisca is unknown, but he is only so unknown because he's only not playing in England because he doesn't have a work permit. If he had one, he would be here!
"There were many English teams, great teams and important, that wanted him. Moreover, there were those who wanted to sign him, even though he could not play for now.
"They wanted to sign him, put him in a minor league [on loan] and hope that eventually he came to be selected [for Brazil's national team], and would consequently then get the work permit."
