Playing just two days after a feisty Premier League match against Arsenal, Manchester City fielded a heavily rotated team and still had too much for second-tier Watford in the English League Cup.

Chelsea thrashed fourth-division Barrow 5-0, with Christopher Nkunku scoring a hat trick and celebrating by inflating a blue balloon and holding it between his lips. Villa won 2-1 at third-tier Wycombe and Leicester triumphed 3-0 in a penalty shootout after a 0-0 draw at fourth-tier Walsall.
