PSG to return for Messi: they will offer him two years with another optional

The months pass by and Leo Messi still remains silent about his future, at least at the moment. He will make his decision at the end of the season and until then he will concentrate on what is happening with Barca, but from the outside clubs are preparing offers to try and convince him to leave. PSG is one of them.
Brazilian journalist Marcelo Bechler of 'TNT Sports', who was one of the first to reveal Neymar's departure to PSG years ago, reports that the French side are working on it and that they already have a contract in place to offer to Messi.
The aforementioned source mentions a contract of two fixed season so that the Argentine can become part of the club's project, with one more season as optional. In other words, if Barca's number 10 chooses to accept, he will play at the Parc des Princes until 37-years-of-age.
This reflects a similar contract offered by Laporta to try and keep Messi at a club which has been his home since the beginning. Two fixed season and one optional - the same as PSG.
Aside from economic conditions and with nothing being signed just yet, Messi won't be able to find any differences between both proposals when he decides to choose his future.
Furthermore, the French side remains the only alternative option for the Argentine after Man City took a step back. Two open offers with very difrerent settings for Leo Messi.
