Ronny Deila has backed penalty row striker John Guidetti as he stressed there would be no cheating permitted at Celtic.
The 22-year-old Swede won and scored a controversial spot-kick in Sunday's 4-0 Scottish Cup win over Hearts at Tynecastle.
The Jambos were incensed when referee Willie Collum pointed to the spot after the on-loan Manchester City forward went down in the box following a challenge from defender Brad McKay.
It is understood the Scottish FA's compliance officer, Tony McGlennan, will not be taking any retrospective action against the Hoops player after viewing footage of the incident.
And ahead of the Scottish Premiership game against Partick Thistle tonight, the Celtic boss contributed his thoughts to the debate.
"Maybe it was not a penalty, but it is a long way from there to diving," he said.
"It looked like he slipped a bit so it is nothing, it is a decision the referee has made."
Asked if Guidetti should have told Collum there had been no contact, the Norwegian replied: "No, as a player you don't know everything that is happening. When you play you play to win and you are so focused on winning.
"We don't want cheats, that's an important thing, but I don't think he was wanting a penalty."
Deila also reiterated his backing of Aleksandar Tonev, whose appeal against his seven-game ban for racially abusing Aberdeen defender Shay Logan will be tomorrow.
The on-loan Aston Villa winger was found guilty by a Scottish FA judicial panel, on the balance of probability, of "excessive misconduct by the use of offensive, insulting and abusive language of a racist nature" during a Premiership clash between the two teams in September.
"We have to do everything in our power to get this away from Aleksandar," said Deila. "We don't believe Aleksandar is a racist. We believe him."
