Most results this term have been ground out, and Vidic takes heart from the fact United can only get better.
"We definitely have a positive feeling," Vidic told Inside United.
"We know that up until the win over Blackburn we hadn't performed as well as we can.
"But from my experience, this sort of time is when we usually come into good form.
"We all want to win the trophy. Last season was very disappointing.
"We just need to keep pushing hard and playing well. If we do that, we have a good chance of regaining it."
