Kon Schramm has revealed that his client could be on his way to Home Park in a bid to revitalise his career after struggling with injury with Munich.
"A loan move to Plymouth is a possibility," said Cooper's agent, Schramm.
"But up to now nothing has been decided just yet. There are still several things to sort out."
The 25-year old USA international spent time as a youth player with English giants Manchester United but failed to make the grade at Old Trafford and found himself in MLS with FC Dallas after loan spells with Academica Coimbra and Oldham Athletic.
