But Carvalhal was disappointed Swansea were not awarded a first-half spot-kick when Mohamed Diame appeared to block a Mike van der Hoorn effort with his arm.
Carvalhal masterminded a League Cup upset at St James' in September 2015 when Steve McClaren was Newcastle manager and he repeated that 1-0 win against Benitez's side in a Sky Bet Championship fixture on Boxing Day 2016.
"I must be honest, I didn't see it [the penalty claim] at the time", he told a news conference.
The Newcastle manager also revealed that he would have a number of players who would not be able to feature against the Swans, although offered some positive news regarding some of them.
"So we are not thinking of selling those that are already playing". "In 10 seconds, the video referee would give a communication saying, "Stop, penalty and red card", I am absolutely sure".
Newcastle currently sit precariously in 14th position in the Premier League table, just three points clear of the drop zone, and their lack of goals is now becoming a genuine concern. "Without doubt Newcastle need to sign a striker, they are desperate for a striker, they do need to score some goals". Yes, but maybe you would have to pay £25million or something like that.
"His attitude has been really good".
"I didn't like the last five minutes when we were making some wrong decisions and giving them the chance to play on the counter-attack".
West Ham United have been linked with midfielder Jonjo Shelvey, though Benitez said after the FA Cup win over Luton Town that the chances of teams fighting relegation doing business with each other was unlikely.
He added: "When you are not winning a game like this one, so important, any player has to be disappointed if they do not continue playing".
"And we're not planning to sell anyone who we consider can make a difference to the team".
"I didn't have any problem with it".
