Green failed to force his way into England's final squad for the friendlies against Switzerland and France following the arrival of Capello in January.

And the shot-stopper has again been overlooked for the forthcoming meetings with USA and Trinidad & Tobago on May 28 and June 1 respectively.

Green admits that he could simply have failed to impress Capello and he fears he could be set to remain in the international wilderness while the Italian is in charge of England.

"There is a distinct possibility," Green told Sky Sports News when asked if could continue to miss out under Capello. "I'm failing to do so, so far.

"It's life. All I can do is focus on what I'm doing and, thankfully, I have had a good season at West Ham and hopefully I'll improve on that next season."

Green has earned one England cap to date which came when he appeared for 73 minutes in the friendly with Columbia in New Jersey in 2005 when the national side was under the management of Sven-Goran Eriksson.
