Leicester City new signing Wilfred Ndidi made his debut apperance for the foxes as an Ahmed Musa inspired side came down from a goal down to beat Everton.
The game also featured new signing for Everton Ademola Lookman being presented to the crowd at Goddison park.
Everton led when Romelu Lukaku turned in substitute Gerard Deulofeu’s cross from close-range in the 63rd minute – but optimism that they would beat a top-flight team at this stage of the competition for the first time in 29 years was swiftly extinguished.
Musa, a first-half replacement for injured Leonardo Ulloa, scrambled home an equaliser within three minutes then linked brilliantly with Danny Drinkwater to beat Everton keeper Joel Robles with a crisp finish after 71 minutes.
Everton were unable to respond and the final whistle from referee Martin Atkinson was met with jeers as manager Ronald Koeman’s hopes of challenging for a trophy in his first season in charge disappeared.
