Vale come to the City Ground just one point behind Forest and with the home side needing to put on a performance that erases the memory of Saturday's FA Cup exit to Chester City.
Foyle said: "The pressure is on Forest, and if we keep it quiet and 0-0 for 20 minutes I am sure their supporters will turn.
"Supporters do turn very quickly and I think they are after one or two personnel there. But it is not always the manager's fault, players never hold their hands up."
