When Juan Martin Hernandez will be free to join another club and which club may be?

Juan Martin Hernandez is playing with the jersey 12 at Stade Francais, David Skr�la is the 10 or Lionel Bauxis are the current fly-half from the club, but JMH had played with Los Pumas as such and in the Heineken Club he had played as 10 because Skr�la was injured.
