Leicester boss Claudio Ranieri had no doubt his side were victims of a "bad" decision by referee Mike Dean in their 1-0 loss at Burnley.
The goal that condemned the Foxes to their third straight Premier League defeat came in controversial circumstances in the 87th minute when Clarets substitute Sam Vokes fired in from close range.
Dean allowed the effort to stand despite Leicester's protests that the ball had struck Vokes' arm before he took his shot.
And Ranieri - whose champions are now 16th, just two points above the relegation zone - said after the match: "Today was a battle and we battled, face to face.
"Only the bad decision of the referee.
"And then, what can we say? Sometimes it is a good decision for us, sometimes it is a bad decision. It is football and we can say only, 'go back and work more'.
"We can say it was handball, but the referee didn't see."
When it was put to Burnley boss Sean Dyche that his side had "got a break" in terms of the goal, he did not dispute it, saying: "We have had some hits go against us, some decisions go against us, which have meant a lot, a change in the outcome."
He then added: "I think tonight it has come off his (Vokes') stomach first before it hits his arm."
Dyche was keen to speak about two incidents earlier in the game that saw Dean opt not to award penalties.
In the first half Burnley fans cried out for a spot-kick after Michael Keane failed to make contact when trying to head the ball as he was challenged in the air by Danny Drinkwater.
Regarding that, Dyche said: "Keano gets a definite push in the back as he is honestly trying to head it.
"If he falls on his face, rolls around and throws his arms up in the air, the ref is under pressure to give a penalty.
"It is tough to take, but I want my players to play in that fashion - I don't want them to jump around on the floor. So that's the way it goes. Sometimes the things go against you."
It was Leicester fans then unsuccessfully appealing for a penalty after the break when Jamie Vardy went down having collided with Tom Heaton - and Dyche commended Dean for taking no action.
He said: "I will say, the referee got questioned tonight, but what a fantastic bit of refereeing with Jamie Vardy and our goalie, because his (Vardy's) leg goes out into an unnatural position - I've seen it back.
"So it is fantastic to see through that, and not give a penalty. I'll commend him on that, because that is not easy to do."
The result - Burnley's seventh successive win at Turf Moor in all competitions and fifth in the league - leaves Dyche's men ninth in the table, 10 points clear of the drop zone.
