In a thrilling first round of the Capital One Cup, seven Championship clubs were knocked out by lower-league clubs.

The shock of the night happened at Griffin Park where Brentford were thumped 4-0 by League Two outfit Oxford United. The visitors raced to a three-goal lead inside 12 minutes as Liam Sercombe scored his first goal for the U’s from 18 yards, before Brentford goalkeeper Jack Bonham’s clearance cannoned off Danny Hylton and went into the net. Kemar Roofe then picked up Bonham’s headed clearance and scored a magnificent 40-yard lob. John Mullins then slotted home a fourth in the 54th minute to ensure Oxford went through to the second round.

Tom Bradshaw’s hat-trick earned Walsall a dramatic win over Nottingham Forest in a seven-goal thriller at the City Ground. Bradshaw struck twice early on but Tyler Walker pulled one back with a tap-in for the Reds. Romaine Sawyers appeared to have won the match for the Saddlers as he fired home a third with 11 minutes left. But substitute Michail Antonio scored a rocket from 25 yards before he backheeled the equaliser in the 90th minute. However, Bradshaw was brought down by Kelvin Wilson in the fifth minute of stoppage-time inside the box and converted his penalty to dump out Forest.

The shoot-out entered sudden death but Curtis Davies scored and Crooks blazed his kick over the bar, meaning Steve Bruce’s side have made the draw for the second round.

Blackburn Rovers lost 2-1 at home to League One outfit Shrewsbury. James Collins gave the away side the lead, but Liam Lawrence headed into his own net to put the two teams level. Just two minutes later Tyrone Barnett volleyed Shrewsbury back in front and they held on for a place in the next round.

Liam Noble’s spectacular brace helped Notts County to a 2-1 win over Huddersfield.

Bristol City were also knocked out as they lost 3-1 away to Luton. Jack Marriott scored twice and Paul Benson once for the League two outfit, before Aston Villa loanee Callum Robinson scored a consolation goal for the Robins.

Byron Moore scored the only goal of the game to give Port Vale victory over Burnley. Bolton were also knocked out as Matthew Palmer’s deflected strike was enough for Burton Albion to win the first ever competitive meeting between the two sides.
