Ray Clemence has warned Manchester United keeper Ben Foster he must be playing regularly this season to be considered part of Fabio Capello's World Cup plans.
Foster only has two England caps to his name but has been tipped by club manager Sir Alex Ferguson to claim the England number one jersey for next year's World Cup in South Africa.
David James has been Capello's number one choice since the Italian took over in 2007 but doubts remain over the Portsmouth stopper's consistency.
He will also be 40 years old by next year's tournament and Ferguson last week backed Foster, 13 years James' junior, to become England's number one despite his relative inexperience at United and at international level.
Clemence, who is Capello's goalkeeping coach, believes, however, Foster must seriously challenge United number one Edwin Van der Sar to put himself in contention for a place in the World Cup squad.
Clemence said: "To play international football you need to be playing games on a regular basis and that is his target this year: to get the opportunity to play consistently in the team.
Then what he has to do is take that opportunity and say, `Sorry Edwin, you're not having your place back'."
