It is not hard to spot the most enticing fixture in the second round of the FA Cup – assuming both MK Dons and AFC Wimbledon win their first-round replays against Cambridge City and York City respectively. It would be the first time the two clubs have met since MK Dons were controversially created in 2004, nine months after Wimbledon's relocation to Milton Keynes.

Wimbledon fans, who watched their club fall into administration, strongly opposed the move and the subsequent renaming of the side and instead founded a new club, AFC Wimbledon. The two sides have nearly met in the second round before, only for MK Dons to lose a first-round replay against Stevenage.

However, while the tie would be billed as a grudge match in some quarters, Wimbledon fans would not necessarily welcome it, given their fury at the way their club was destroyed by the move to Buckinghamshire.

Chelmsford, who play in the Blue Square Bet South, have been rewarded for their victory over Colchester United with a trip to Crawley Town. Crawley, who beat the Metropolitan police 2-1 on Saturday, are third in League One and will fancy their chances of reaching the third round having made it as far as the fifth round last season.

Paolo Di Canio said he wanted to fine his Swindon Town players after their shock 2-0 defeat at home to non-league Macclesfield Town and the Italian's mood will hardly have been improved by Steve King's side being handed a relatively comfortable draw against either Guiseley or Barrow. Equally Harrogate Town, who upset League Two's Torquay United, will be pleased with a home draw against Hastings United, who play in the Isthmian Premier Division.

Hereford United, who entered FA Cup folklore when Ronnie Radford's stunning goal beat Newcastle United in 1972, pulled off another upset on Saturday, beating League One's Shrewsbury Town. However, the Blue Square Bet Premier side face a daunting trip to Cheltenham Town, who are third in League Two. They were 3-0 winners at home against Yate.

Micky Adams, who was Sheffield United's manager when they were relegated from the Championship in 2011, will face his old club to Bramall Lane. The Blades, who were beaten on penalties by Huddersfield Town in the League One play-off final last season, won 2-1 at Bristol Rovers, while Adams' Port Vale won 3-2 at Forest Green.

Adams joined Vale after leaving United following their relegation to the third tier of English football. His Port Vale side are currently second in League Two, five points behind Gillingham, but Adams will probably expect a frosty reception from fans of his old club.

Slough Town are the lowest side left in the competition but will have to beat Mansfield in a replay at home to set up a tie against either Lincoln City or Walsall, who drew 1-1 at The 12th Imp Sincil Bank Stadium.

Dorchester Town, who play in the Blue Square Bet South, produced another upset when they beat League Two's Plymouth Argyle on Sunday. Jake Gosling, who was released by Plymouth when he was 16, settled the tie for the home side. It was a miserable afternoon for Plymouth, who were reduced to 10 men inside the first 10 minutes following Conor Hourihane's red card. Dorchester will play either Luton Town or Nuneaton Borough next.

Gloucester City and Leyton Orient's match as well as Braintree's encounter with the League One leaders Tranmere were both postponed. Alfreton and Chesterfield await the respective winners of those ties.
