#4 Thierry Henry
One of the greatest footballers to join the MLS, Henry had an incredible career before moving to the USA. Multiple Premier League and La Liga titles, a Champions League winners' medal, a World Cup title, in 1998, and a European Championship with France in 2000.
At the prime of his career, Henry was one of the top five strikers in world football. He left both Arsenal and France as their all-time top scorers; not bad when you consider he started off as a winger during his time in Monaco.
After two excellent seasons, Henry hit a lean patch in his third campaign with Barcelona in 2009-2010, managing only 4 goals as other players were preferred. After a slow start in New York, he began to show his ability of old. From 2011 to 2014, the Frenchman was named an MLS all-star and his displays lit up the league.
Everything was done with flair, everything was performed in the best way that Thierry Henry knows, with a swagger. Although he never won the MLS Cup, Henry had a Supporters' Shield win in 2013
