Arsenal and Chelsea are through to the quarter-final of this year’s Carabao Cup. The Gunners defeated Leeds United 2-0 in what was a straightforward affair at the Emirates Stadium on Tuesday night. Two second-half goals from Callum Chambers, who scored with his first touch off the bench and Eddie Nketiah, sent Mikel Arteta’s men through. Chelsea needed penalties to see off Southampton, after their tie ended 1-1 after 90 minutes. Kai Havertz opened the scoring for the Blues, but Che Adams equalized immediately after the break. Kepa Arizabalag was the hero again for the Stamford Bridge side, as they won 4-3 on penalties. Sunderland are also through, after they won a shoot-out against Queens Park Rangers.
