Thiago Alcantara says a Spain squad mixing youth and experience are desperate for Euro 2020 to begin after disrupted preparations for the tournament.
Luis Enrique's side get their campaign underway on Monday when they take on Sweden at La Cartuja in Seville.
Their planning for finals was thrown into disarray when Sergio Busquets tested positive for coronavirus last week, which forced the senior squad into isolation amid fears of an outbreak.
Diego Llorente returned test results later confirmed to be a false positive, while the Under-21 squad were used for the friendly match with Lithuania on Tuesday.
The senior players are due to be given COVID-19 vaccination jabs on Friday and no further positive cases have been identified, meaning Luis Enrique should have a strong group available for selection against Sweden.
Liverpool midfielder Thiago accepts the build-up has been far from ideal but is now eager to get the tournament underway.
He told Marca: "Football has changed. Beyond talent, it will be the teams who are best prepared who will compete. We're talking about the best players in Europe at the best tournament.
"We've gotten used to playing under pressure. We're a very young team but used to that level of competition. The youngsters give us veterans a hunger to compete.
"There's another very important thing: we're very invested in what the coach asks of us. That comes from a long time ago, not from now. We're a hard-working team and we're hungry.
"I know [Luis Enrique] from the Barca youth system. He has very clear ideas. He loves the pressure after losing, possession... and winning, which is what we all want.
"The good thing about Luis is that he is always the same. He's no different depending on who he talks to."
Thiago insisted the Spain players coped well with the news of Busquets and that they are far more used to such situations than in the early stages of the pandemic.
"We're used to this situation. It's been a year and a half of living with COVID. We've been accustomed to training individually or collectively, but always with the objective of competing," he said.
"Fear was experienced in the first stage of the pandemic. It was an uncertainty on a global level. We didn't know what was going to happen.
"I was in Germany with my family and yes, there was that feeling of fear. Not here. We have great professionals around us and we comply with all the protocols they ask us to follow."
