Ferguson said: “Maybe there will be a sense of what may have been when Ronaldinho comes here but we know at this club someone else always turns up.
“We thought we had Paul Gascoigne and he changed his mind and went to Tottenham so we signed Paul Ince and he was fantastic.
“Then we tried to get David Hirst and Alan Shearer but got Eric Cantona, and what can you say about that? We thought we had an agreement with Ronaldinho until some events changed the course of history and we got Cristiano. It’s amazing, football.”
