Francis scored the winning goal in the 1979 European Cup final for Nottingham Forest, shortly after becoming the first British player to be the subject of a £1 million transfer fee.
He won 52 caps for England between 1976 and 1986 and shared a pitch with Robson at the 1982 World Cup in Spain.
The two were also opponents at the highest level of English football for a number of years and were close personal friends.

“As a person he was a great lad, a fantastic player,” Robson said.
