1st of all you're naming mostly LBs not LWBs, might as well include all the LMs and LWs in the mix. 2nd of all Coentrao, Evra, Sandro is just ridiculous, no way those guys were better than Asamoah in his prime. Coentrao was a backup, Evra and ManUnited had a horrible horrible season and Sandro had worse stats in a way worse league.
rest are at least debatable, I agree on Felipe Luis and Alaba being superior at the time
