England World Cup winner and Manchester United legend Sir Bobby Charlton has been diagnosed with dementia.
Sir Bobby, 83, won three league titles, a European Cup and an FA Cup with United during 17 years at Old Trafford.
"Stay strong, we love you," said United striker Marcus Rashford.
His wife, Lady Norma Charlton, expressed the hope that the knowledge of his diagnosis could help others.
Manchester United said in a statement: "Everyone at Manchester United is saddened that this terrible disease has afflicted Sir Bobby Charlton and we continue to offer our love and support to Sir Bobby and his family."
Rashford, 23, said on Instagram: "Sir Bobby, you are my hero and I am devastated that you are having to go through this.
"I filmed alongside this man as a child and was in awe. I still am when I see you. This man, from day one, was everything I wanted to be. Kind, professional, caring, talented."
