Hyndman understands the club has lost a great player in 24-year old forward Cooper and knows the importance of bringing a suitable replacement which he plans to do.
“There is a plan," Hyndman said. "We've done a lot of work and put a lot of time into this.
“Unfortunately, a lot of the players we identified as pretty doggone good already signed because this thing went longer than we thought it would.
"Our fans deserve the best player we can possibly get, so we'll try to find a quality player with some experience."
Dallas are expected to pocket up to $3million depending on Cooper’s performance with his new club.
