I mentioned on this forum back in May I think it was I had contact with someone who knows someone very senior at INEOS and they have been working on the deal since before "strategic alternatives" was announced, I was told 18 months before and that the deal would take many months but its pretty much a foregone conclusion, they also said SJ feels like its been set up to extract more cash from INEOS.
Second source I spoke to, probably around a month or so ago, or whenever the Tour De France was, separate person, someone very close to me, very well respected in cycling and was there reporting on team INEOS spoke to "someone" high up, told them November, they are buying the club and "these things take time".
Take as you will, but that's where my confidence comes from. Both from INEOS side of things so that could be a factor but both separately said its INEOS and not "if" but "when". For what its worth id prefer 9-2 and SJ so I wasn't too pleased.
