The Belgian champions went undefeated across their final three matches in Group D, coming from three goals down to draw 3-3 at Arsenal and defeating Galatasaray 2-0, before clinching a late 1-1 draw away to Borussia Dortmund on Tuesday.
After Ciro Immobile gave Dortmund the lead just before the hour-mark with a sharply-taken goal, Aleksandar Mitrovic clinched a share of the points for the visitors in the 84th minute, heading Anthony Vanden Borre's cross home at the back post.
"Tonight I expected my lads to make up [for poor league performances] and that's what they did," Hasi said, according to uefa.com.
"It was important to make amends but now we have to confirm this good performance against less glamorous opposition.
"If we continue like this, we can still go places this season."
"This Champions League campaign has been extraordinarily positive, I want to congratulate my players on it," the Albanian said.
"It has showcased our football, something we last had at Anderlecht in 2000-01. We must not forget that we have one of the youngest sides in the Champions League and at times we were able to play refreshing attacking football.
"Now we wait to see who the draw pits us against in the UEFA Europa League but first we will focus on the Belgian Pro League."
