Leicester boss Claude Puel was left frustrated after their 3-1 defeat at Arsenal.
Puel was unhappy his team were not awarded a first-half penalty for a handball by Rob Holding.
Puel also felt the Gunners defender should have received a second yellow card for the offence.
“I think of course we deserved another result, we played a brilliant first half, a fantastic performance with good quality, discipline and structure,” said Puel.
“In this game all the bad moments went against us.
“It was a penalty and a second yellow card (for Holding). This could change the game of course.”
Puel confirmed striker Jamie Vardy was removed late on due to a stomach bug as Leicester finished the match with 10 players on the field.
The Foxes boss then joked Vardy could not stomach the Holding penalty decision going against his team.
“It’s a stomach problem, yes,” said Puel. “He couldn’t digest the penalty decision!”
