Carabao Cup: Sunderland out; Colchester through

Jo Harrison

Manchester City maintained their grip on the Carabao Cup as they progressed to the quarter-finals with a 3-1 home win against Southampton.

Pep Guardiola’s side, who successfully defended the trophy last season by beating Chelsea on penalties, were rarely troubled by the Saints, who were looking to restore lost pride after last Friday’s 9-0 thrashing by Leicester.

Nicolas Otamendi’s header and Sergio Aguero’s 11th goal in 12 appearances this season put City 2-0 up at half-time.

Aguero grabbed his 12th of the campaign early in the second period before Southampton, who improved in the second half, responded through Jack Stephens’ header.

Ralph Hasenhuttl’s side return to the Etihad Stadium on Saturday in the Premier League.

Burton failed to repeat last season’s heroics, when they reached the semi-finals, as they were beaten 3-1 at home by Leicester.

Goals from Kelechi Iheanacho and Youri Tielemans inside the first 20 minutes put Leicester in control before Liam Boyce pulled one back for Burton early in the second period.

James Maddison struck a late third for the Foxes, who have won six of their last seven games in all competitions.

Everton reached the last eight following a 2-0 home win against Watford, with Richarlison scoring against his former club.

Mason Holgate’s header broke the deadlock for Everton midway through the second half and Brazilian team-mate Richarlison lashed home their second in stoppage time.

Sunderland’s Will Grigg and Marc McNulty both failed to convert from the spot as Oxford won 4-2 on penalties after a 1-1 draw at the Kassam Stadium.

Oxford, who dumped West Ham out after winning 4-0 in the previous round, led at the break through Rob Hall’s effort before McNulty equalised for Sunderland with 12 minutes left.

James Henry, Anthony Forde, Tariqe Fosu-Henry and John Mousinho all converted in the shoot-out for Oxford, while Grigg blazed his spot kick off target and McNulty’s effort was saved.

Colchester extended their run into the latter stages of the competition with a 3-1 win at Sky Bet League Two rivals Crawley.

Dannie Bulman’s curling first-half finish for Crawley was cancelled out two minutes later by Luke Norris’s header.

Michael Luyambula’s own goal early in the second half gave Colchester the lead and Luke Gambin added their third.
