Moyes admitted he was gobsmacked to learn this was the first time the duo have started together in a Premier League match for United.
He said: "The two boys could easily be the two centre backs for England in the World Cup.
"Both of them could play in Brazil. Things can change. I think the future will probably be with Jones and Smalling as the two future England centre backs.
"They will certainly be competing with the other Manchester United centre backs to start for this club."
