Such a tough choice but as we are playing a 4231, it has to be Messi. We should do all time XI's for a few nations as well. Hate seeing some of the Brazilians missing out.
Greatest RW of all time: Garrincha But the formation chosen was a 4-2-3-1. One can play without wingers; and therefore, Lionel Messi is a must. I would rather have Lionel Messi as my RAM than Garrincha as a RW in a 4-2-3-1 formation. My vote goes to MESSI.
