Even though all the three sides - Delhi Daredevils, Victoria and Wayamba finished their Group D proceedings with a win and a loss each, Mubarak's men lost out on the next stage spot on the basis of net run rate.
Mubarak feels his team was little late in adapting to the conditions, which eventually proved to be fatal for them.
"Right now I have bit of mixed emotions. We were little slow to get our acts together. We just started getting our acts together and are out of the tournament. Adapting to the conditions was crucial," Mubarak said after the match. "We should have got our acts together against Delhi," he added.
Meanwhile, Victoria pacer Shane Harwood, who picked up three wickets for just 14 runs on a tricky Ferozeshah Kotla pitch, said they wanted to keep a clean slate in the 12-team tournament and today's defeat have made them disappointed.
"We are little bit disappointed to lose the match. We never wanted to qualify in this way but at the end of the day we are through and that matters most," Harwood said.
"We were just lucky hat we won the first match," he added.
Asked whether Victoria batsmen was under pressure while chasing the 83-run mark, needed to qualify for the next stage, the right-arm pacer said, "We didn't have that in mind. We just wanted to win the match, but definitely knew the target."
He also insisted that the pitch was never easy to play on and not the ideal one for a batsmen to play shots from the beginning.
"It is very difficult to score runs if you bowl straight. It is a difficult wicket to chase. But once a batsmen is set, it becomes easy to score runs," Harwood said.
