Arsenal stunned in Carabao Cup loss to fourth-tier Fleetwood Town - ESPN

Premier League champions Arsenal were knocked out of the Carabao Cup after a stunning loss to fourth-tier Fleetwood Town following a penalty shootout Tuesday.

Bruno Guimarães had his spot kick saved by Jay Lynch before Fleetwood's teenage defender Conor Haughey lashed home an emphatic penalty to spark a pitch invasion at Highbury Stadium as the League Two side triumphed 5-3 in one of the greatest upsets in the competition's 66-year history.

Asked what was going through his mind before taking the decisive penalty, Haughey told Sky Sports: «I don't know — just pick my spot and put it in! Top corner and then just run.

»We've just beaten the Premier League champions, it just shows how good this team are."

It is the first time that reigning Premier League champions have been knocked out of the League Cup by a fourth-tier side. Eighty-four positions separate the teams in the English football pyramid.

The match finished 1-1 in regulation.

«I don't think it will [sink in],» Fleetwood manager Matt Lawlor told Sky Sports. «I've just told the players to enjoy it and we've got a league game on Saturday. I didn't want to be the bearer of reality, but we've got a game.

»I couldn't believe it. The biggest night in the club's history in terms of opposition coming to town and we've managed to beat the champions somehow."

Arsenal didn't field a full-strength team — first-team stars such as Declan Rice, Gabriel and David Raya were missing — but manager Mikel Arteta still picked a strong lineup containing seasoned internationals, with captain Martin Ødegaard even thrown on at halftime with Fleetwood leading 1-0.
