France coach Raymond Domenech admits he does not know where the danger will come from when Les Bleus face Brazil in Frankfurt on Saturday evening in a World Cup quarter-final.
In a rematch of the 1998 World Cup final, won 3-0 by France, Les Bleus will be looking to progress to the semi-finals at the expense of the team that regained the world title four years ago in Japan.
France adopted a brilliant strategy to beat Spain 3-1 in last Tuesday's last 16 match in Hanover but Domenech admits that Brazil have so many star players that it will be more difficult against the Latin Americans.
Asked if he planned to man-mark Ronaldinho, the FIFA World Player of the Year, Domenech said: 'We have someone to muzzle Ronaldinho, someone to muzzle Kaka, one for Adriano, one for Cafu.
'Roberto Carlos and Ze Roberto are not bad either and for free-kicks we will have to look at their defenders who are good in the air.
'We have everything under control - it's a plan to muzzle 13 or 14 players but saying it is one thing, doing it another.'
Asked if the Brazil match was special, Domenech told a press conference: 'It's a World Cup quarter-final. Any World Cup match is a special event. The further you go in the competition all the more so.
'The last 16 match (with Spain) was special, so was the Togo game. Even against Cyprus, Switzerland or the Republic of Ireland in qualifying they were events with a lot of pressure.'
Domenech looks likely to persist with the same line-up that started against Spain - the first time he will have kept the same side since arriving in Germany.
Playmaker Zinedine Zidane, who will quit after the tournament, and full-back Willy Sagnol both trained normally on Friday after having problems earlier in the week.
Domenech admits Brazil will be tougher opponents than Spain, saying: 'It's not easy to play Brazil. No-one has ever beaten them.
'We will have to be at the top of our game if we are to have a chance.'
The match will see Zidane, who turned 34 during the World Cup, duel with Ronaldo - the two players who have been the emblematic figures of the previous two World Cups.
Zidane's two goals in the 3-0 win over Brazil in the 1998 final made him a worldwide superstar while Ronaldo, who has scored a world record 15 goals at World Cup tournaments, scored both goals in the 2-0 2002 final win over Germany and finished the tournament top scorer with eight goals.
