Diabate and Kelechi Iheanacho both struck twice as Leicester advanced with a 5-1 win at Peterborough in another result which was favourable for our followers.
Onyinye Ndidi also got on the scoresheet in the latter stages as Claude Puel's side brushed aside their League One opponents at the ABAX Stadium, Matt Brocklebank having weighed in with a hefty bet on over 2.5 goals - which was paid out after half an hour.
Foxes boss Claude Puel said: “It was a good experience to start the game well, especially after what happened against Fleetwood. It was a good response and a good cup game. We showed good quality and good play. It's important to give young players game time so they can show their qualities for the future. These young players can be the future of Leicester City.
“It was a good game with good quality. We knew it would be a tough cup game with all the rain and the wind. It was important for us to show good quality and have some good battles.
“It was important to play good football and we scored fantastic goals in the first half. We tried to keep control of the game. It was good to put an opponent with quality under pressure. We scored early and kept good control to prevent them coming back into the game."
