Harry Potter: Quidditch Champions

I struggled with this achievement for a while. Most people suggested to sit behind the hoops and intercept the shots, but I often found it would result in stealing the ball instead.

The method I used was:
1) Set the opponent's to the easiest difficulty
2) Select the Chaser
3) Follow the opponent Chaser (with the Quaffle) as close as I possibly could without tackling them
4) As soon as they throw the Quaffle, use the tackle button and you'll hopefully intercept the shot

It took a few tries but this method worked best for me!
