The American shot-stopper racked up over 100 appearances in three seasons for the Foxes, cementing his status as one of the more respected goalkeepers in City's Premiership days.

Born in Washington, Keller started his career with the University of Portland and had four international caps when he crossed the pond to London and Millwall in February 1992. He spent four years as a Lion, getting used to the English game, but made the move to Leicestershire following Millwall’s relegation.

He proved to be a superb shot-stopper and cemented his place as first-choice ‘keeper at Filbert Street as the club, under the guidance of Martin O’Neill, looked to become an established club in the top-flight.

He was just one appearance short of 100 in the Premiership and also kept goal during City's stint in Europe, while he produced a top-drawer display in the League Cup Final Replay at Hillsborough as the Foxes won the competition. In the original match, he become just the second American to play in a big domestic final at Wembley behind John Harkes, who featured for Sheffield Wednesday in 1993.

Keller’s success in England was noticed back in his home country, too, with the US Soccer Federation naming him as their Player of the Year in 1997. That progressed to two appearances for his country in the following year’s World Cup in France.

On the expiry of his contract the American wanted to try his hand on the continent and secured a move to Spain and Madrid, although not with Real or Atleti, but smaller Vallecas-based Rayo Vallecano. He spent two years there, helping Rayo punch above their weight in the top flight of La Liga before returning to England with Tottenham Hotspur. Ironically, he featured for Spurs at Filbert Street and became the last goalkeeper to concede a goal there before City's move to a new stadium.

Another move to the continent followed with German club Borussia Monchengladbach and while he was with the club he played a key role in the USA’s Gold Cup success, won on a penalty shoot-out against Panama.

One last professional move to England followed with Fulham before Keller moved home to finish his playing career with Seattle Sounders, where he captained them to US Open Cup success in 2009.
