Musa as shout is good as is Wynn who could provide cover at CB and LB.
By memory, he has played more as a left sided CB than LB the last 2 - 3 years.
Musa is the cracking bench at Minnesota, and getting a few minutes here and there.
He has a green card I'm pretty sure.
An American fiancée. Don't see him interested in moving back home any time soon.
Edit - Think if you are looking to the US, Wynne (likely to be cut adrift by Rapids), Kyle Adams (not made one Houston squad this MLS season) or Brotherton (maybe on the radar of some MLS clubs, but maybe not), are I would think possibilities.
All younger than Musa as well.
