Leicester manager Paulo Sousa described the 5-1 friendly win at Peterborough as a huge improvement.
Substitute Steve Howard scored twice with DJ Campbell, Andy King and Dany N'Guessan also on target as City romped to an impressive victory against their League One opponents.
"I am very happy to see such a huge improvement and it is something which we will keep building day by day to get the results we want," said Sousa.
"We showed a better intensity and tempo and with our decisions on the ball. We have started to grow and want to keep doing so because this is the way I want to see it.
"It was not just because we won 5-1 but we also created a lot of other chances. There was a huge improvement too in our offensive organisation."
