Manchester City striker Sergio Aguero was not likely to be banned for his tackle on David Luiz, assistant boss David Platt believes.
Aguero will not face retrospective action over his two-footed challenge on the Chelsea defender in Sunday's FA Cup semi-final victory at Wembley.
With referee Chris Foy having awarded a free-kick at the time of the incident, the Football Association considers the matter to have been dealt with.
Some pundits have said the tackle warranted a red card but the FA does not like to 're-referee' incidents which have been seen by officials.
Platt said: "I wasn't surprised, based on the rules the FA has put in place if the officials have seen it.
"There have been precedents set, and not only have precedents been set, they've actually gone on record and said if that's the case - I wasn't surprised.
"The rules are the rules. We don't make them up, we adhere by them."
City manager Roberto Mancini has felt his team have suffered from some poor decisions this season, most notably when captain Vincent Kompany was sent off against Arsenal in January.
The defender's red card was later overturned on appeal.
Platt has dismissed a suggestion that luck has evened itself out.
He said: "I don't know if it's luck and whether we've had it. What is luck? I am not sure.
"It is a situation that has gone. I am not surprised he has got off. They are the rules, the officials saw it."
Platt was speaking on Mancini's behalf at a press conference to preview the midweek Barclays Premier League game against cup final opponents Wigan.
Playmaker David Silva, who missed the game at Wembley with a hamstring injury, has all but been ruled out and is more likely to return against Tottenham this weekend.
Platt said: "The game on Sunday was a bit too early for David.
"I think if we had pushed we probably could have got him ready for tomorrow evening but it would still be a risk.
"I think we will probably be pragmatic about it. We will see how he feels today but I think we'll probably give him a full week's training before the game at the weekend."
Right-backs Micah Richards and Maicon are both back in contention after knee injuries.
The pair are both in training and Richards, who has been out since October, was a member of the group that went down to Wembley. Maicon did not travel due to illness.
Midfielder Jack Rodwell, sidelined for the past month with the latest in a series of hamstring injuries, is also in contention.
