Former FIFA president Sepp Blatter last year claimed some past UEFA draws have been rigged.

He suggested some balls were kept warmer than others so the right ones were paired together.

UEFA dismissed the "completely absurd" claims while Blatter was adamant heated balls didn't exist at FIFA draws.

WORLD CUP DRAW LIVE STREAM: How to watch the draw

Asked ahead of the draw, which takes place today, about heated balls, FIFA director of competitions Chris Unger said: “There's no truth to that.

"They're all the same; they don't feel any different, they don't look any different with the exception of the red balls, which are there for a purpose.

“It's entirely random and by chance how the groups get formed at the end.”

The draw will be done today by former Manchester United striker Diego Forlan, who attended a rehearsal this week.

He is confident of his own country’s chances and said: ”South American teams are very strong,.

"Every team is tough. I think it's going to be like previous World Cups. I hope Uruguay can win.”

FIVE OF THE MOST LETHAL WORLD CUP GROUPS OF DEATH

Express Sport look at five other groups of death in World Cup history.

1970 (Brazil, Czechoslovakia, England, Romania)

The term 'grupo de la muerte' was coined for this group by journalists in the host nation Mexico. England were world champions at the time, Brazil had won it in 1958 and 1962 and the Czechs were the team Brazil beat in the 1962 final. England were defeated 1-0 by Brazil in the searing heat of Guadalajara, in a match famous for Gordon Banks' incredible save from a Pele header, Bobby Moore's sublime tackle on Jairzinho and the image of Moore and Pele swapping shirts at the end.

England made it out of the group but West Germany exacted revenge for 1966 in the quarter-finals. Brazil won the World Cup for a third time, and the line-up that thrashed Italy 4-1 regularly wins 'greatest team of all time' polls.

1982 (Argentina, Italy, Brazil)

Slightly different to all the other groups featured here, as this one came in the second stage of the finals in Spain. It pitted a free-wheeling Brazil side featuring the likes of Zico, Falcao and Socrates against an Argentina team featuring Diego Maradona, plus eventual winners Italy.

Italy and Brazil both beat Argentina and their head-to-head encounter was a classic settled by a Paolo Rossi hat-trick. The Azzurri advanced to the semi-finals as group winners and beat West Germany in the final.

1986 (Denmark, Scotland, Uruguay, West Germany)

Alex Ferguson's Scotland faced a daunting task in Mexico as they took on 1982 runners-up West Germany, the great 'Danish Dynamite' side featuring star names such as Michael Laudrup and Preben Elkjaer and reigning South American champions Uruguay.

Denmark topped the group by winning all three of their matches, including a 6-1 hammering of Uruguay, but the Germans went the furthest by again reaching the final - this time losing to Argentina. Scotland led 1-0 against West Germany as Gordon Strachan tried - and failed - to vault an advertising hoarding in celebration but ultimately lost 2-1, and took their solitary point against Uruguay, who had Jose Batista sent off in the first minute.

2002 (Argentina, England, Nigeria, Sweden)

David Beckham and England were pitted against Argentina - the team against whom Beckham had been sent off in the previous World Cup and who had knocked England out. An opening draw against Sweden heaped extra pressure on the game against Argentina, which was settled by a Beckham penalty. England drew their final group game with Nigeria and got through to the quarter-finals, where they were undone by Ronaldinho's free-kick for eventual winners Brazil.

2014 (Costa Rica, England, Italy, Uruguay)

Greg Dyke, the Football Association chairman at the time, famously made a throat-slitting gesture at the time this draw came out, and it ultimately proved lethal for England who were out after defeats to fellow former world champions Italy and Uruguay. Playing Italy in the extreme humidity of the Amazon jungle in Manaus didn't help Roy Hodgson's men.

Uruguay also fell by the wayside and star striker Luis Suarez sank his teeth into the shoulder of Italy defender Giorgio Chiellini in their final match and was given a nine-match international ban.
