Maksim Shatskikh scored a brace and Timur Kapadze, Ulugbek Bakaev and Aziz Ibragimov added a goal each as the central Asians bounced back from their opening 2-1 loss to Iran to put themselves back in contention for a place in the last eight.
It was the biggest ever win recorded by the Uzbeks at the AFC Asian Cup but Inileyev was not completely happy with the performance of his side.
"I am not 100% satisfied with our performance although I felt that we played at a very good level today and I am pleased with the result that we got," said the Uzbek coach.
"I never thought that we could win 5-0 so this is a very good result for us. But perhaps the most important thing is that we showed good form and we collected three points."
Inileyev’s main concern was the ability of his side to maintain their fitness levels throughout the duration of the match in the energy-sapping heat and humidity of Kuala Lumpur.
"I am satisfied with our performance and the five goals that we scored but we had some problems that we will try to resolve before our next game.
"It is very hard to play for 90 minutes in this type of climate and that is why in the middle of the game, our form dipped.
"But our physical training here has helped us to get used to the conditions and I felt today that we maintained our strength for a longer period than we did in our last game.
"If we can bring together all of the good things that we have done in our games so far, I believe we can do better in our next game against China."
