Wigan's historic win over Man City in the 2013 FA Cup final - Martinez reminiscesThe non-league clubs dreaming big
York City (home v Wigan Athletic, Friday, 19:45)
It's 10 years since Wigan defeated Manchester City in the final. Since then the Latics have bounced around the Championship and League One. Will they come a cropper at York, 19th in the National League, in front of the live BBC cameras?
Alfreton Town (home v Walsall, Saturday, 12:30)
Part-time Alfreton, ninth in National League North, have never reached the third round. They will have to get past League Two Walsall if they are to make club history but will have the backing of around 2,500 home fans in Derbyshire.
Maidstone United (home v Barrow, Saturday, 15:00)
Like Alfreton, Maidstone are also from the sixth tier of English football. They are managed by George Elokobi, who played in the Premier League for Wolves. Will he mastermind an upset against League Two's in-form club Barrow, who face a near 700-mile round trip?
Barnet (away v Newport County, Saturday, 15:00)
Barnet did the double over Newport the last time these two sides met in League Two in 2017-18. And the non-league club - third in the National League - will be confident of returning from Wales with another victory and a place in the third round for the first time since 2019.
Horsham (away v Sutton United, Saturday, 15:00)
Will Horsham make the most of their second chance in the FA Cup? Beaten by Barnsley in a first-round replay, they won a reprieve after their opponents were removed for fielding an ineligible player. Defeat Sutton, bottom of League Two, and the club from the seventh tier will be in the third round.
Eastleigh (home v Reading, Sunday, 13:30)
Reading are in free-fall. In League One's relegation zone, they face a tricky tie at National League Eastleigh. It is only two seasons ago that the Royals, a Premier League club 10 years ago, were eliminated by non-league Kidderminster Harriers.
Chesterfield (home v Leyton Orient, Sunday, 14:00)
Chesterfield are flying in the National League. Eleven points clear at the top, Paul Cook's side will be eyeing another upset against League One opponents after knocking out Portsmouth in the first round.
Aldershot Town (home v Stockport County, Sunday, 14:00)
Stockport are top of League Two but will not be relishing a trip to Aldershot after the National League club scored an incredible seven goals at League Two Swindon in the previous round.
Yeovil Town (away v Wrexham, Sunday, 15:45)
Wrexham and Yeovil were National League rivals last season but while the Welsh club were promoted to the Football League, Yeovil were relegated to National League South.
Ramsgate (away v AFC Wimbledon, Monday, 19:45)
Ramsgate, who play in the eighth tier, are the lowest ranked side left. The Isthmian League South East side, who have pocketed £63,069 in FA prize money for reaching this stage, will be dreaming big when they face AFC Wimbledon from four leagues above.
