Major League Soccer (MLS) is one of the fastest growing soccer leagues around the world. The league's quality and competitiveness has signifanctly increased in the past few years with the signing of several renowed players from Europe and South America.

There have been many international stars that have played in MLS, such as David Beckham, Zlatan Ibrahimovic, Thierry Henry, and Andrea Pirlo. However, they were all free transfers and it was not until recently that MLS clubs began to make big money transfers.

Since 2014, many teams have opened their checkbooks to bring in valuable players that would improve the league instead of signing free agent superstars who may not be fully invested in MLS. Here we list the 10 most expensive signings in MLS history to date.

Just like Inter Miami's inaugural MLS season, Rodolfo Pizarro's signing left a lot to be desired. David Beckham's forked out $12 million for the Monterrey star, but the Mexican was a shell of himself in his first year in South Beach. He was sent on loan to Rayados, but now he's back in Miami trying to prove his worth.
