Neymar showed exactly why he is seen as the main man to helping Brazil win a World Cup on home soil for the first time, with a brilliant performance for the Selecao in their friendly against Panama Estadio Serra Dourada on Tuesday.

The Barcelona forward was instrumental in almost every goal scored by Brazil in the 4-0 victory, with the youngster opening the scoring with a trademark freekick.

Neymar himself won the setpiece on the half hour, before dispatching the ball into the back of the net with panache to set Brazil on their way.

Dani Alves made the scoreline 2-0 five minutes before halftime, rifling home a wonderful effort from the edge of the box, before Hulk got in on the act early in the second half to triple the lead.

Neymar was the creator of that third goal, with a cheeky backheel from the 22-year-old allowing Hulk to produce an assured first-time finish with the outside of his boot.

Chelsea midfielder Willian added the gloss to the score with a strike in the 73rd minute after another move from Brazil orchestrated by Neymar.

"Everyone knows Neymar's talent," Brazil coach Luiz Felipe Scolari said. "But he always comes up with something new to surprise."

Despite the big win against, albeit weak opponents, Scolari believes there is still a lot of improvements to be made by his side before their World Cup opener.

"I am still concerned. We are getting better -- but we know we have a fair way to go," Scolari added on FIFA's official website. We were a bit off colour in the opening minutes and it could have been different had we been playing a superior opponent. Afterwards, we improved.

"The run out was worthwhile but we must up our rhythm and be a lot better for the Croatia game."

In other friendlies, Switzerland picked up a 2-0 victory over Peru, while the match between Greece and Nigeria ended in a stalemate.

Switzerland are expected to spring a surprise or two after their impressive performance in the World Cup qualifiers, and they did their reputation no harm by topping their South American opponents.

Juventus defender Stephan Lichtsteiner opened the scoring for the Swiss with a header in the 78th minute, before Bayern Munich midfielder Xherdan Shaqiri made it 2-0 six minutes from time.
