If you're like me and you didn't have a controller or friends to play with there is an alternative in Single player.
From the main menu go Local play--Single player--level 1-1 (this will be the only one available)
Make sure you win the first game (1-1). After you've won the first game choose level 2-1. In level 2-1 you'll be playing a 1v2. Simply let the AI's run around with the ball and they should naturally get it in.
If you're having trouble try getting the ball and throwing it down underneath your own goal, the AI's should chase it down and quickly past it to one another in order to score a quick goal. When they pass it to one another you will see a doted line and it'll say on your screen "Alley Oop!".
Edit: Please understand you might not achieve this in one game! It took me 2 game attempts in order for it to unlock.
Also please tell me why you down voted the solution in the comments, thank you.
