Next manager who is available.....
You've got to assume the club are pretty close to a new appointment having sacked PH and I'd expect an announcement in next day or two.
Bielsa is the one the media are all touting but I'm not too sure myself whether that will come to fruition.
Ranieri, unlikely but available.
Others:
Allardyce
Moyes
Pardew
Laudrup
McCarthy
Club have said they want someone exprienced and they won't be taking someone in a job I wouldn't have thought so for me its got to be one of them, I don't see anyone else with experience. Personally from our limited options I'd happily have Moyes.
