No new contract offer given to Messi yet - like you said, 65 days until his existing one finishes.
I presume that Laporta's promises were based on the Super League coming off and them being given this £300m welcome bonus. If they did, great - offer Messi a new contract using it with the promise of using the rest to improve the squad and make them competitive in Europe.
Without that money. Barcelona are what they were last Summer when he wanted to leave: skint. They've competed domestically this season and may well win the league in addition to the CDR but they still suffered in Europe. Including a battering at home by PSG.
Even if he wanted to stay now (despite not much changing in terms of why he wanted to leave) then I don't see how they can afford to pay him unless he accepts a massive wage cut and other promises. They either give Messi a new contract or use that money to put a small dent in the debt or improve the squad as a whole.
No idea what will happen personally but my rose-tinted glasses when it comes to him point to him leaving and being left with 2 choices: us or PSG. Again, I think he'd choose us but that could be bias (Pep etc. over Neymar).
