E.ON, the official energy partner of The Football League, is giving two lucky customers the chance to visit United's training ground - with four family members or friends - to watch Kevin Blackwell's boys be put through their paces.

The prize doesn't end there, as the lucky winners will then be driven to Bramall Lane, to enjoy a full, behind-the-scenes tour of the stadium.

For your chance to win this fabulous prize, simply visit eongreatsaves.com, register on the site and then test your knowledge by playing 'A Question of Saves'.*

Remember, the prize is exclusive to E.ON customers only.

The competition closes on Wednesday 3rd March 2010.

If you're not an E.ON customer, don't worry, there are still some fabulous prizes up for grabs through the Spot the Save competition. Simply visit eongreatsaves.com for a chance to win a mascot place for your child or a family ticket for four people to The FA Cup Final.*
