Never heard of the of source, but this isn't the first time this summer we've been linked to this kid. English, but unfortunately wouldn't count as a HG. Does appear from vids to be a more athletic CB, which would certainly be the type to appeal to Poch and his high line.
Some guys on SC have been posting translated posts from a Sporting board, and it does appear as though they're quite upset about this news. Seem very hopeful it's not true. Would seem to bode well for us if it is.
