He was the beacon of hope, despite what has happened around, and above him.... He provided comfort, regardless of the pain elsewhere. Another abject, sorry, messy episode...and all NUFC fans deserve so much more. Photo: Catherine Ivill

There will be a huge backlash from the supporters. They loved Rafa and the work he had done with limited resources. He wanted to develop the club, he is a manager used to competing for the biggest trophies. Photo: Laurence Griffiths
