England manager Sven-Goran Eriksson expects midfielder Steven Gerrard to play in their World Cup opener against Paraguay on Saturday. "Everyone is fit," Eriksson was quoted as saying by BBC on Friday. "Gerrard trained very well and should be on the pitch if there is no reaction to his back injury overnight." The Liverpool captain, who missed the previous World Cup through injury, joined England's training on Friday alongside Wayne Rooney. The 26-year-old midfielder suffered a back injury and said earlier that he has a 50-50 chance in starting England's opener against Paraguay on Saturday.
