With the big news breaking today that Leo Messi will be leaving Barcelona, the sporting world has gone into overdrive suggesting where he may end up.

From Paris, to Manchester, to even Los Angeles, there's no shortage of quality internet work being done. While in soccer, it's not uncommon for players to move, the size of the name in this scenario warrants a double take.

It's gotten us thinking. Over the years, the AFL has increasingly gone down this path, with player movement in the off-season becoming the norm.

The move would have a lasting impact, with the Cats challenging for the flag almost every year since. The Crows on the other hand lost their biggest weapon and so began an exodus of talented players from the club over the following seasons.
