John Harkes became Sheffield Wednesday's first ever American when he arrived at Hillsborough from the US Soccer Federation in December 1990. The fee, as reported by Jason Dickinson in the book Sheffield Wednesday Miscellany, a mere $185,000.
Later that month, he announced himself on the scene with a 35-yard piledriver in the Owls' 2-1 League Cup win over Derby County (which you're encouraged to relive here) and started the final against Manchester United five months later, which ended in a 1-0 win to Ron Atkinson's then second-tier side.
Wednesday were promoted the following month (later allowing Harkes to become the Premier League's first ever American) and returned to Wembley two years later, gracing the home of English football four times in six weeks. However, the Owls lost 2-1 to Arsenal in both domestic cup finals, though Harkes was on target in the League Cup showpiece.
The popular midfielder was sold to Derby four months later, but the club's fondness for Americans has not waned, as Frank Simek and Stuart Holden will testify.
