It was a night of shocks in the Capital One Cup on Tuesday, none more so than at Griffin Park where Oxford United humiliated Championship side Brentford 4-0.
New Bees boss Marinus Dijkhuizen chose to make 11 changes from the weekend. However, that decision backfired on the Dutchman as the League Two visitors - who won the competition in 1986 - raced into a three-goal lead after just 12 minutes, Kemar Roofe with the pick of their goals from 40 yards.
Elsewhere, there was a remarkable seven-goal thriller at the City Ground as Walsall stunned Championship side Nottingham Forest 4-3.
Forest had trailed 3-1 at one point, before drawing level at 3-3 thanks to a late brace from Michail Antonio, only for Tom Bradshaw's 95th-minute penalty to complete his hat-trick and send the League One team through to the second round for the fourth successive season.
Meanwhile, there was another huge upset at Vale Park as League One Port Vale knocked out Championship side Burnley, who were a Premier League side last season.
Rob Page's Vale won thanks to a goal eight minutes from time from Byron Moore, which saw the home team through to the second round.
Blackburn Rovers were also on the end of a shock result as they were beaten 2-1 at Ewood Park by League One Shrewsbury Town. The home side had trailed early on, only to equalise through Nathan Delfouneso's strike, but Tyrone Barnett's second goal of the night sent the visitors through to the next round.
League Two Hartlepool eliminated Fleetwood of League One thanks to Billy Paynter's second goal in two games since joining the club, while another shock occurred at the John Smith's Stadium as Notts County beat Championship side Huddersfield Town 2-1.
Murray Wallace put the home team in front, but Liam Noble scored twice for the visitors, who even survived Gill Swerts' red card to progress to the next round.
And finally Luton Town overcame Bristol City 3-1 - their first win in the League Cup since 2007 - with Jack Marriott's brace helping to knock out the Championship side, and Jimmy Floyd Hasselbaink's Burton Albion beat Bolton at the Macron Stadium thanks to Matt Palmer's deflected 25-yard strike late on.
