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.

With this in mind, we decided to take a look at the some of the biggest moves the AFL has ever seen.

Not just in size of the name, the money or the destination. But in terms of the impact that it had. Here are the ones we think have created the biggest splash over the years.

2. Ron Barassi

It's been called the biggest transfer in footy history. Ron Barassi leaving Melbourne to captain-coach Carlton had an immense impact on the entire competition.

After a period of success, losing a star like Barassi shook the Demons to their core, having not won a flag since his departure.

As for the Blues, after a lean period, Barassi led them to two flags, cementing himself as a legend of the game.

The move signaled a new era of professionalism in footy, as Barassi was paid a wage to be Captain-Coach. The flow on effect down the years is immeasurable.
