'Unfazed' Foster prepared for action.
The Manchester United keeper has been drafted into Fabio Capello's squad as back-up to David James.
And with the Italian intent on using all six substitutes in the final warm-up before next Wednesday's key World Cup qualifier against Ukraine, there is a decent chance Foster might find himself involved at Wembley.
Although in match terms the 25-year-old does not have much experience - he has not played a Premier League game since playing for United in a win at Derby last season - he knows what it is like to appear on a major stage.
In 2006 he was part of the Watford side that reached the Premier League by beating Leeds in the Championship play-off final, and just under a year later made his England debut against Spain at Old Trafford.
Last month he was crowned man-of-the-match in United's Carling Cup shoot-out triumph over Tottenham at Wembley.
Foster said: "I really enjoy playing the big games.
It is not something that fazes me. I don't feel the pressure or get nervous.
"It could be an FA Cup third-round tie away at a non-league ground. You still have to do the same things."
