The on-loan Benfica attacker is eagerly anticipating this weekend's match against the Catalans, and believes the Blaugrana are no longer the strongest team on the planet
Real Madrid coach Jose Mourinho pointed out earlier this week that the Blaugrana are no longer Spanish nor European champions and the Portugal international has echoed his compatriot in stating that the Camp Nou club are no longer the benchmark upon which other sides should measure themselves.
"Barcelona aren't the best team in the world," Oliveira said according to Marca. "I think they're up there with the best, but Madrid are also a great team, albeit with a totally different playing style to Barca, but they have a great team too.
"We're going to give it our all and go all out against them, because that's the only way you can beat Barcelona. They have a great team, but we have quality too and we'll have to see what happens.
"Overcoming Barcelona won't be an impossible" task, but it will be difficult because they have an incredible squad and they're very tough to beat. They don't really have any weaknesses."
Saturday's encounter is scheduled to kick off at 22:00CET.
