League One club Burton Albion reached the League Cup quarter-finals for the first time in their 68-year history after defeating Nottingham Forest 3-2 on Wednesday (AEDT).
The unheralded their-tier club from central England - formerly home to Socceroo Jackson Irvine - were joined in the League Cup - also known as the EFL or Carabao Cup - last eight by Premier League team Bournemouth.
Bournemouth continued their strong start to the season with a 2-1 win over second-tier Norwich City, headlined by a superb strike from Junior Stanislas to open the scoring.
The last 16 was already the furthest Burton had reached in England's second club knockout competition, with Nigel Clough's team having upset top-flight Burnley and second-tier Aston Villa.
Forest - Clough's former team as a player - became their latest victim, with an own-goal and strikes by Scott Fraser and Jake Hesketh giving Burton a 3-1 lead.
While Forest reduced the deficit in injury time, Burton held on.
Bournemouth is also defying expectations by sitting in sixth place in the Premier League after 10 games, and the south-coast team also could have a trip to Wembley Stadium to look forward to.
Fielding a largely second-string team, Bournemouth went ahead through Junior Stanislas and clinched victory through Steve Cook's goal in the 72nd, two minutes after Norwich's equaliser.
It's only the third time that Bournemouth have reached the quarter-finals of the League Cup competition.
Leicester were scheduled to play Southampton in the other match on Wednesday (AEDT), but it was postponed after the death of Leicester's owner, Vichai Srivaddhanaprabha, and four other people in a helicopter crash on the weekend.
On Thursday (AEDT), Chelsea, Arsenal and Crystal Palace play lower-league opposition in Derby County, Blackpool and Middlesbrough, respectively, while there's an all-Premier League game between London rivals West Ham United and Tottenham Hotspur.
Defending EFL Cup champions Manchester City hosts Fulham on Friday (AEDT).
