"To win the title is one thing but we want to achieve something special so our main target is to win back-to-back titles," said Vieira.
"If you want to be successful and you look at Manchester United in the 1990s or Liverpool in the 1970s and 1980s, they won the title two, three or four times in a row and that makes you a great team.
"We have to do it too. We are capable of that though and we have the hunger and determination to do it. We want more trophies and more success as we're a special team."
