Andre Villas-Boas admits his insistence he is at Chelsea for the long haul would carry more weight if publicly backed by the club's hierarchy.
The 34-year-old Blues boss reiterated he was confident Chelsea owner Roman Abramovich would not sack him should he fail to reach the Champions League quarter-finals and that his three-year project to revamp the squad had the Russian billionaire's "full" backing.
Ahead of Tuesday's clash with Napoli, Villas-Boas suggested he was beginning to sound like a broken record in his claims of unequivocal backing, and that the words would carry more weight "coming from the top".
In front of watching chairman Bruce Buck and chief executive Ron Gourlay, Villas-Boas said: "You have to understand that this club, from 2004 up to now, has made a dramatic change for the best in terms of their past.
"It's the richest part of Chelsea's history, full of trophies and success, and you want to perpetuate that into the future. To do that, you have to sometimes make changes because you cannot sustain the same habits that you had in 2004, when this environment and team was created to make a winning team.
"These words would be more valuable coming from the top. I cannot keep saying them but, as the voice of the club, I will continue to perpetuate this message because this is what we believe in."
Villas-Boas, who has overseen what is currently the club's worst season of the Abramovich era, admitted speculation over his future was inevitable based on the Russian's previous habit of firing managers.
He said: "In terms of the results this year, the speculation is normal given the cultural past of this football club, but you have to understand that there's a different perspective now."
The Portuguese added: "I'm really confident about next year. That doesn't take any responsibility for what's happening now, but we had a three-year project to change not only the team, but the culture and structure of the club.
"There's a lot we needed to do, a lot of plans, so that's why I'm excited about the future. Having said that, we have to build a team to win trophies from the start."
