"Gregan is keen to come to Leeds and he's the type of player I believe will be a major addition to our midfield. He commands midfield and is very comfortable on the ball.
"Stern came over from America where he had an excellent scoring record and he continued to do well at Nottingham Forest, his record there got him noticed by Birmingham City and he has continued to get goals in the Premiership.
"So clearly these two players meet the criteria we are looking for, and if we can bring one or both those players in then it will be a boost for the club."
