Not sure Hart could have done anything else considering what's been going on with them for the last 6 months or so, Portsmouth have been doing their best to make Mike Ashley look competent. They'd probably be in the same mess even with Mourinho in charge.
Aye, he had almost a whole new team to rebuild. Look at what they spent ffs:
Aaron Mokoena, free
Jamie O'Hara, loan
Hassan Yebda, loan
Fredrique Piqionne, loan
Aruna Dindane, loan
Michael Brown, nominal fee
Tommy Smith, £1.8m
Danny Webber, free
Anthony Vanden Borre, loan
Kevin Prince Boateng, loan
Steve Finnan, free
Tal Ben Haim, £2m-ish
Mike Williamson, £2.2m
Antti Niemi, free
Only spent around £6-7m, although there could well be loan fees in there I'm not aware of.
