“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,” United said in a statement on Sunday.

The announcement came two days after Nobby Stiles, who won the 1966 World Cup and 1968 European Cup as Charlton’s teammate, died after his own battle with the illness. In July, Bobby’s brother and fellow England World Cup winner Jack also died after being diagnosed with dementia.

“Yet another hero of our 1966 WC winning team has been diagnosed with dementia. Perhaps the greatest of them all @SirBobby. This is both very sad and deeply concerning,” former England striker Gary Lineker tweeted. Bobby survived the 1958 Munich air disaster that killed eight United teammates and was part of the club’s rebuilding.
