Ernesto Valverde told Revista that his primary goal at Valencia is to give the team "personality".
The ex-Athletic Bilbao, Espanyol and Villarreal manager has been installed as Mestalla boss after Mauricio Pellegrino was axed with the side lying 12th in the La Liga table.
"I know if you go to a team in the middle of the season you will go to a team in a crisis, big or small, and you have to get results," said the 48-year-old former striker.
"But the most important thing for me is to give this team its own personality and convince the players that they have to have one style and something to do together to try to win."
Valverde, who guided Olympiakos to the Greek League title in 2009, '11 and '12, says despite Valencia's financial problems they are a club adept at finding talented players.
But he is well aware that, due to the dominance of Real Madrid and Barcelona, Los Che may never return to their halcyon days of the early 2000s, when, under Rafael Benitez's tutelage, they won La Liga twice.
"Valencia is a club with big economic problems but they are competing at a very high level," added Valverde. "And this is the work of Unai Emery (the manager who left the club over the summer) over a number of years.
"They sign very good players like David Villa and Juan Mata and Jordi Alba, who was from the academy of Barcelona - but there is too much difference between Barcelona and Real Madrid and teams like Valencia, Atletico Madrid and Levante.
"It is very difficult to compete with them and you know you have little chance of winning something, except maybe the Copa del Rey. It is not impossible but almost."
