Leicester City eased past MK Dons to reach the Carabao Cup quarter-finals in their first game after the World Cup.
Foxes manager Brendan Rodgers took no risks and played a full strength line-up on the night.
Youri Tielemans and Ayoze Perez gave the Foxes a two-goal cushion by the break before Jamie Vardy added another.
Chances were sporadic for the hosts at Stadium MK and they did not make the most of their few opportunities.
Premier League Leicester were a step above and their sharpness in the final third was too much for the League One side to handle.
