Oscar, arguably, made a name for himself when he joined Chelsea from Internacional in 2012. The attacking midfielder played 203 times for the Blues, scoring 38 goals along the way. In his spell with the west London outfit, he won two Premier Leagues, one Carabao Cup, and one Europa League - before moving to the Chinese Super League in 2017. Incidentally, many big names have joined Messi in the MLS and Oscar would add to that illustrious list if he followed suit.
