Look "vi12zas783js" this video was uploaded by a user who is maybe impressed by his amazing attacking talent; It's not my fault that he didn't add some defensive actions. Btw, you should've realized from the video that he doesn't pee, too
since you seem to have a hard time dealing with digits i do you a favor and highlight some words by writing them with capital letters. i hope it helps you to understand...
oh yeah, blame the guy on youtube for it. YOU said you THOUGHT he was an AMAZING TALENT (as left back) from THIS youtube VIDEO. So obviously you're criteria to judge a full back have nothing to do with defending otherwise you would have said "he looks great while attacking, but i don't know if he can defend". it is ok if that is YOUR DEFINITION of a full back.
this is what YOU wrote
He seems an amazing talent from that YouTube video. I hope Secco gets him.
following your logic we could go for this french TAIWO guy that has fancy videos of him shooting the shit out of french goalkeepers.
i think we need a full back that sticks to his position and does not make the central of attack even more crowded (with del piero, amauri, diego and giovinco we already have players that don't really like to play on the wings).
i think knowing how to defend and delivering crosses is more important than a player that likes to play through the middle and will more likely shoot than supply our aerial beast (amauri) with proper assist.
