SIR Bobby Charlton has joined the rest of the football world in mourning the death of Sir Bobby Robson. The United legend said: "I am very sad like everyone else in football. Bobby Robson was such a genuine person, he was so kind and generous. "I can't say enough about him. Even in his last few years when he was so ill, to still consider other people rather than himself is just unbelievable. "I will think of him as someone who was always gracious, always kind whenever I wanted to speak to him. "And he has just been magical for the game. "He was so in love with the game in any shape or form that he will be unbelievably missed by everyone." Sir Bobby Robson's family say they have been "humbled and overwhelmed" by the number of tributes that continue to flood in. Tearful football fans have turned one end of Newcastle United's St James' Park stadium into a shrine for the footballing knight. Thousands braved early rain on Saturday to lay flowers, flags and banners in the Sir John Hall Stand, turning it into a sea of colour. A spokeswoman for the family said: "The family is humbled and overwhelmed by the public response to his passing." Newcastle confirmed the stand at the north end of the stadium would remain open between 9am and 5pm daily all week to allow more people to pay their respects. A club insider estimated at least 15,000 well-wishers had visited the ground since Sir Bobby's death on Friday at the age of 76. Pre-season matches across the country at the weekend were preceded by expressions of respect - including a minute's applause and chorus of Sir Bobby's name by Sunderland fans before their friendly against Celtic.
