Leicester City face Manchester United at Wembley
Last season's league champions will meet FA Cup winners Manchester United in the Community Shield at Wembley.
The last time the sides met at England's showpiece venue was the 1963 FA Cup Final, which United won 3-1.
New United manager Jose Mourinho says the trophy will "have meaning" for those of his players who were part of the FA Cup-winning side last season.
"We're ambitious but know it will be very hard," added Foxes boss Ranieri.
"I forgot what happened last season. Now my focus is on the new season."
Morhino however has a poor record in this fixture and lost 1-0 to Arsenal last year and by Christmas he was no longer Chelsea boss.
Leicester have won the traditional season-opener just once, beating Liverpool in 1971, when they were invited to take part as second-tier champions after double winners Arsenal pulled out.
Ranieri says he has a full strength squad to choose from, with forward Jamie Vardy back in training after featuring for England at Euro 2016.
"All managers and players want to play at Wembley Stadium. It's one of the most famous stadiums in the world," he said.
"This is not a friendly. We will give the maximum and also Manchester United will too. Both teams want to win it."
Mourinho, who replaced Louis van Gaal in the week following United's FA Cup win against Crystal Palace in May, has been left frustrated by his side's pre-season.
A game against Manchester City in China, scheduled for 25 July, was called off after heavy rain ruined the pitch.
"The week of no work in China was really bad for us," said Mourinho. "So we need to train, we need to play, we need minutes for the players.
"Now we have no chance to train against other teams. We have Leicester before the Premier League and it is not a training session - it is a game.
"We have to face it as a game. We have the chance to give minutes to some people. Some who I know cannot play for 90 minutes, but of course we are going to try to win it."
