Forrest is a confirmed target for Tottenham boss Harry Redknapp.
But Hooper told the Scottish Sun: "James is a top player who we need at the club. Defenders can't live with him up here. His final ball is good so hopefully we can keep him. He has a good ten yards of pace and gets the ball into the box. He also scores goals so you can't ask for much more.
"I just hope we can all stay together."
