They made the best possible start by winning the Community Shield against Wigan, but Vidic knows the questions will keep coming.
"People are questioning everyone," he said.
"People are asking whether we can win the trophy again. Can we still be champions?
"That is not just about the manager, it is the players as well. Can the players perform the same way as they did before?
"We are trying hard to show what we can do. We have a good work ethic to start with and everyone wants to put themselves back into contention.
"Most importantly, I see the hunger.
"I am pleased with that because we will definitely need it if we are going to achieve what we want this season."
