Arguably the two biggest superstars fighting outside the UFC right now are Dan Henderson and Alistair Overeem.
Overeem is a former Strikeforce heavyweight champion and was recently stripped of his belt and released from the promotion.
UFC President Dana White has gone on record saying that the UFC is in talks with Overeem right now and they are working on signing him.
Henderson is the current Strikeforce light heavyweight champion, but isn't contracted for any more fights with the promotion and has not yet signed a new contract.

Whether or not either of these fighters will sign with the UFC remains to be seen, but it would definitely be a smart move for both men.
