Disastrous. Those ‘at the top’ of our great club should be ashamed. The great shame is that they won’t be. The way they are repeatedly able to snatch defeat from the jaws of victory is astonishing. Thank you Rafa. Mike Ashley - get out of OUR club. Photo: Jeff Spicer

A world class manager. A manager who performed so well in very difficult circumstances. A manager who understood the fans. Thanks and good luck Rafa, you were brilliant for the Toon. #SHAMBLES Photo: Stu Forster

If I was every single player at Newcastle I would ask for a move away! They are, at boardroom level a joke!! I feel so sorry for the fans with M Ashley in charge. Wouldn’t mind Gattuso or my favourite would be S Gerrard. Photo: Clive Mason
