Watched by a noisy crowd of around 3,000 Carlos Parreira's defending champions held a one-hour practice session which Ronaldo and Cafu, recovering from injury, came through unscathed.

Before the session began Ronaldo appeared to contradict his coach's upbeat take on his physical wellbeing 24 hours earlier when he admitted he was still not in top form.

It's been over a month since the forward turned out for Real Madrid scoring his 100th goal for them but tearing a leg muscle in the process.

However he insists by the time Brazil's title defence starts against 1998 World Cup semi-finalists Croatia on June 13 he'll be raring to go.

AC Milan defender Cafu, a veteran of three World Cups, for his part said he was suffering no ill effects from the knee surgery he underwent earlier this year.

Ronaldinho meanwhile is bracing himself to be singled out by the opposition who will be eager to nullify the World footballer of the Year's deft footwork in the stadia of Germany next month.

"I am prepared for that, but I think I won't be the only one. The opposition will also be worried about other players, and are going to create difficulties for us."

The brilliant Barcelona midfielder reckons he's matured since his part in helping Brazil win the 2002 World Cup which included a fine goal against England in the quarter-finals.

"I'm more mature now. Many things have happened since, I've learned some things. I'm at a good stage of my career."

Ronaldinho and the rest of the south American giants will remain in Switzerland until June 4 before moving to their World Cup base camp in Germany.

Whilst in this town of 3,900 inhabitants beside lake Lucerne Parreira has scheduled friendlies against Swiss side FC Lucerne and then New Zealand in Geneva.

Brazil meanwhile entertained a visitor for lunch - namely Sepp Blatter, the Swiss head of FIFA, world football's governing body, who was accompanied by the head of the Brazil football federation, Ricardo Teixeira.

One of the subjects up for discussion was bound to have been the venue for the 2014 World Cup finals for which Brazil are front runners to host.

Brazil arrived in Europe with expectations high back home with 79.8 percent of Brazilians polled in a CNT/Sensus survey reckoning they will return with a record sixth world title.

A mere 1.1 percent believed Brazil's perennial arch rivals, Argentina, would bring back the coveted trophy.
