Bernardo has revealed a mood swing at Albion.

From a preoccupation with relegation to the prospect of a "good season" if the Seagulls stay up and reach Wembley in the semi-finals of the FA Cup.

Since Bernardo regained the left-back spot from Gaetan Bong, Albion have beaten Huddersfield and Crystal Palace back-to-back in the Premier League.

That has put a different complexion on the frame of mind of the players for tomorrow's FA Cup quarter-final at Millwall.

Bernardo said: "Football sometimes is so funny.

"If you look two weeks ago, the atmosphere was completely different. We were really worried about relegation and are still because we're not safe and the cup was Plan B, almost a Plan C.

"Right now, things have switched and we're a bit more comfortable and we start to see things from a different perspective.

"From something that could be a terrible year fighting against relegation, now we are already looking to go to a semi-final to go to a final.

"One hundred per cent, if we manage to do something bigger and maybe not even go to a final but be in a semi-final, it would be a great achievement for the club and for our group. It would be a good season."

For that to happen Albion must get past Millwall and their hostile supporters, who are also notorious in Bernardo's homeland of Brazil thanks to a 2005 film about football hooliganism.

The Argus: Bernardo (above) said: "The players have told me, but Millwall is very famous in Brazil because of the movie Green Street – or Hooligans, as it is called in Brazil. I don’t know if it is a good thing or a bad thing, but Millwall is known in Brazil because of the movie and it is connected always with their fans.

"So, for sure, my team mates told me about the fans, but I already knew about the atmosphere they brought to the stadium so I am very excited about playing in their ground."

Concerns are growing again about behaviour in England after a Birmingham supporter ran onto the pitch and threw a punch at Aston Villa's Jack Grealish.

The FA, Premier League and English Football League issued a joint statement yesterday condemning such incidents and promoting the Football Supporters' Federation's "passion not poison" call to respect opposition clubs and fans.

Even so, Bernardo says in Brazil, far from regarding the English as hooligans, the authorities are in fact revered for stamping the problem out.

He revealed: "Because of the problems we have in Brazil with the hooligans, England is seen as a role model of how to solve these problems.

"Because in the 80's, the 90's I guess it was as bad as it is in Brazil right now.

"If you put on Sky Sports Brazil or Fox Sports and they have a debate, talking about violence in the stadiums, England is always mentioned as a role model.

"So we don't see you guys as hooligans, not at all. The (Premier) League is the most appreciated league in Brazil, the one that everyone watches.

"The fans are not the warmest ones compared to the South American ones, but you still have a lot of credibility because of the problem that you solved with the hooligans."

Although Bernardo, 23 (below centre right), has experienced no serious safety issues as a player, he witnessed a lot in Brazil as a supporter and when he moved to the Bundesliga.

The Argus: He said: "I was a fan of Sao Paulo and I have seen pitch invasions, fireworks thrown on to the pitch, that kind of stuff.

"In Brazil I played for a small club, Red Bull Brazil, and I didn't face anything really bad because there were not many people in the stadiums.

"In Germany, Leipzig is a very hated team. We weren't really in danger but they did a few things with us.

"There was a cup game where they threw a pig head on the pitch and there was one time at Leverkusen where they attacked our bus with paintball weapons.

"They were more like pranks than putting us at risk.

"People here take football more as entertainment. People like to joke, they don't get annoyed so easy, that's what I see.

"In Germany, they take football a bit too serious at times. It's like a science so I enjoy more the English way of seeing football.

"I have played in tough places, especially in Brazil and Germany. What happened last week with the pitch invasions is something that is very isolated.

"It is something that unfortunately cannot be avoided completely, but I consider England a really, really safe place and the fans in general are really polite.

"They know the rules and they know that if they do something wrong they will be banned or face some kind of consequence, so I am really not afraid of that."
