The Citizens were said to have invited Halford to join them in the Royal Box at Wembley to lift the FA Cup after their victory over Stoke.

"Even as his health deteriorated, he was a familiar face at the City Football Academy or at the Etihad Stadium.
"In reflecting on his life, I am reminded of the enormous pride he - and we - took from him being able to realise a boyhood dream by lifting the FA Cup in 2011. It was a special moment not only for Bernard, but for everybody connected with Manchester City .
