The result means that they are now third in Group J but only two points behind leaders Lazio, who were held to a 1-1 draw against Panathinaikos.
"It is obviously not the full result we wanted bearing in mind the draw between Lazio and Panathinaikos, but certainly we will take a point," Villas-Boas told reporters.
"The group is completely open. What we face now is two games at home and I think we are in a good position in the group."
