When it comes to designated players, Wayne Rooney was their most famous DP signing in 2018. The Designated Player Rule, often called the Beckham Rule, allows MLS teams to sign up to three players whose salaries exceed the salary cap charge, with the club and/or a third party paying the difference.
Designated Players are typically the highest-profile and most talented players on an MLS roster. They are expected to be difference-makers on the field and ambassadors for the club off it. The DP rule has been instrumental in bringing world-class talent to MLS, elevating the league's profile globally.
