The EFL Cup fourth round ties were more than eventful as the night saw Manchester United, West Ham United and Southampton move into the quarter-finals. The results were in stark contrast to the weekend performances from Chelsea and Manchester United.

Mata scored the only goal of the match as Manchester United bounced back from their humiliating defeat to Chelsea with a 1-0 Derby victory over holders Manchester City at Old Trafford.

In the second half, United went close through Paul Pogba after the Frenchman latched on to a through ball from Ibrahimovic, but was brilliantly tipped onto the left-hand post by Caballero. In the 54th minute, United got their breakthrough when Ibrahimovic's squared pass was slotted home by Mata. Despite the goal appearing to have come off together between Ander Herrera and Fernando in the box, it was allowed to stand. 

The late introduction of Sergio Aguero and Raheem Sterling failed to make any impact for Guardiola as City were unable to find an equalizer to force extra time. With this loss, Guardiola's win-less streak reached six games which is an all-time low in his managerial career. He also has fitness concerns over skipper Vincent Kompany, who was withdrawn after half time after returning midweek from a long-term injury.

Slaven Bilic's West Ham recorded a memorable 2-1 victory over city rivals Chelsea at the London Stadium after goals from Cheikhou Kouyate and Edimilson Fernandes fired the hosts into the lead. Gary Cahill pulled one back for Chelsea. But the cup tie was marred by angry fans destroying a section of the stadium seats.

Chelsea looked comfortable for most of the first half but they were rocked by Kouyaté’s goal just before the break. The defender met Mark Noble’s cross, after West Ham recycled a corner and sent in a strong header past Asmir Begovic.

The hosts doubled their lead within three minutes into the second half as a lightning counter led to Dmitri Payet drifting in a pass for Edimilson Fernandes, and the Swiss midfielder finished it from 20 yards. Chelsea squandered two great chances as Willian and Costa failed to make the most of them.

Meanwhile, Southampton edged out  league strugglers Sunderland 1-0. The Saints' record £16m signing Sofiane Boufal's stunning strike in the 66th minute helped them secure a place in the quarter-finals.

In the quarter-finals, Manchester United will host West Ham while Southampton travel to London to face Arsenal. Jurgen Klopp's Liverpool, who beat Tottenham on Tuesday, will face Championship outfit Leeds United while Hull City take on Newcastle United.
