Leicester and Arsenal are still searching for their first Premier League wins of the season after sharing a 0-0 draw on Saturday, with the champions left fuming after two penalty appeals were denied.
A tight first half came to life in the final minutes when Danny Drinkwater was fouled in the Arsenal penalty area but referee Mark Clattenburg waved away frantic appeals.
Fox substitute Ahmed Musa was brought down in the 88th minute, only for Clattenburg to again wave play on.
Arsenal defender Rob Holding was unconvinced that Leicester were hard done by.
The £2m new signing said: “[Musa] went down hoping for it. I think it was the right decision.”
Gunners boss Arsene Wenger went on to praise Holding as his transfer policy was questioned again.
Wenger said: “It’s not just about spending the money. We are ready to spend the money but we have to find players who will improve our team.
“Nobody speaks about the performance of Rob Holding today, he is English, he is 20 years old, you should be happy, but I’m sorry he didn’t cost 55 million pounds.”
