"It is amazing in these four games we have not had a goal - I bet the public are hoping we do not meet in Rome," Fergie said after the match.
"I do not know how that is because we are an attacking side and Villarreal have a great record themselves.
"It is unusual for four games to end up 0-0.
"I thought we carried a bigger threat than them tonight. We had better opportunities in the match.
"But we are satisfied we are into the next stage. That's want we wanted to achieve. We have an advantage over Villarreal now.
"We have a home game against Aalborg and they have to go to Celtic so hopefully we can win the group."
