Think Dennis Wise was at Watford v Reading recently, but you could read anything and everything into that. I doubt his position is safe at the club anyway, haven’t really heard much but it sounds like these new guys are listening to the fans with talk of Keegan & Shearer. And they don’t want Wise so I can’t imagine he’d be scouting around for a new manager.
They might well have to appoint Keegan regardless, until the end of the season anyway, as I think most managers would be quite reluctant to take the job right now. Remember, the transfer window’s shut and if things don’t improve then Newcastle may well find themselves staring at relegation by the time the window opens. And that’s not an attractive prospect for any big names out there.
