Lazio president Claudio Lotito is confident proving critics wrong this season.
Lotito remains at loggerheads with ultras over his handling of the club.
"The transfer strategy over the summer helped to bring important resources into the squad," said Lotito.
"We are working on a concrete, targeted and precise project aimed at improving the opportunities of a club that, considering its history, deserves great recognition.
"I am certain we will soon prove our qualities, contrary to the naysayers who want to dismantle this club and never really wanted what was best for Lazio.
"I have no doubts that this Lazio side belongs in Europe. We must improve, refine our mentality and find that unity that Coach Stefano Pioli will undoubtedly be able to transmit to the group."
