The last time a top-flight side were knocked out of the FA Cup by non-League opposition, it was a bricklayer who scored the winning goal.
Sutton Town's Matt Hanlon, who despatched Coventry City in 1989, was following a distinguished tradition featuring a geography teacher, Mickey Mahon, who scored Wimbledon's goal against Burnley in 1975, while Ronnie Radford, a Hereford United hero against Newcastle in 1972, was a carpenter.
Those days are long gone. The non-League team which runs out at Goodison Park today includes a former colleague of David Beckham at Los Angeles Galaxy and a one-time England Under-17 team-mate of Jack Wilshere. Tamworth may have little pedigree in the game, but their players are full-time professionals, either winding down from a career in the Football League's lower reaches or hoping to return to the top levels.
The other non-League survivors in this weekend's third round, Fleetwood, Wrexham and Salisbury, are also full-time. Fitness should thus not be the telling factor today, nor, in many respects, technique. Many of these players have been in the academy system. These days the main difference between a Conference player and one in the Football League is the ability to perform consistently, and to cope with the game's pressures and insecurities.
Having lost five times at home this season, Everton's manager David Moyes will therefore be taking nothing for granted, especially with Phil Jagielka joining Leon Osman, Tim Cahill and Jack Rodwell on the injured list, with Marouane Fellaini probably out too. Everton have never lost to a non-League side, at least not since 1913 when the Football League only had two divisions and they were defeated by Swindon Town, of the then-powerful Southern League. However, Everton needed a replay to beat Altrincham in 1975 after being held at home and, eight years ago, went out to a Shrewsbury Town side soon to be relegated from the League.
Marcus Law, the Tamworth manager, said: "We will prepare and hope, and if it comes our way hopefully pounce. If we can just go and embrace it, enjoy the occasion and understand what the game can throw up, then we'll let the FA Cup gods look after the fixture."
At Highbury ambitious Fleetwood, the only team at home of the quartet, will be pinning their hopes on much-coveted striker Jamie Vardy as manager Micky Mellon faces his mentor, Ian Holloway.
In-form Wrexham, whose most famous giant-killing was as a struggling Fourth Division club in 1992, when Mickey Thomas's free-kick beat the then-champions Arsenal, will travel with confidence to Brighton. Salisbury, the lowest surviving club, go to Sheffield United with player-manager Darrell Clarke pondering whether to pick himself.
