I think PL knows more than he's letting on. If that jet is there because of us, then I imagine it's due diligence and the new owner taking a look around the club and grounds.
If that is true, then PL would know, or he'd have some questions about the random American's looking around his office.
So here's my guess.. He knows and further, he's met the new owners and they've offered him a 1 year contract so they don't have to rush a sale and finding a new manager and expecting the whole club to gel before pre-season.
I'm not ITK.. I haven't got a clue. But that's my guess. Deal is still weeks out, but PL staying on.
