Frustrated by a lack of first-team opportunities at Spurs, Keller has neverthelesss done his best to pile some intense pressure on Brad Friedel for the No.1 jersey.

The former Millwall, Leicester and Rayo Vallecano man was released by his club for the Gold Cup earlier this year.

He played throughout the tournament and conceded just one goal in five games as the USA lifted the trophy beating Costa Rica 2-0 in the final.

An injury to Neil Sullivan has given him a chance for some first-team football towards the end of the season, and Keller is still hoping that he could be selected ahead of Friedel.
