D.C. United of Major League Soccer officially announced on Thursday that long-time England and Premier League star Wayne Rooney is set to move to the club.

Rooney is a big name, having played for over ten years for Manchester United, one of the biggest clubs in the world, and should move the marketing needle for a D.C. United club that is set to open a new stadium soon.

But he is also 32-years-old, and having played professional soccer since he was 16-years-old, Rooney has a lot of mileage on his legs, and his best days as a player are clearly behind him. MLS is not as tough, competition-wise, as the Premier League of course, but it still remains to be seen how effective Rooney will be for a D.C. United club that currently sits at the bottom of the league's eastern conference.

This trade-off between on-field quality and big-name marketability is not new to MLS; the league has often been criticized as a retirement league for its tendency to make splashy signings for over-the-hill stars who may be coming to MLS just to enjoy a glorified American vacation. However, in fairness, some of these signings have gone on to enjoy tremendous success on the field as well off of it, so take a look below and the biggest names to come to the league, and see how each one has fared.
