"We won our first game and it is unbelievable for the fans, coach and all the people in Huddersfield", Mounie told BBC Sport.
When quizzed over the situation, De Boer was not certain a deal would materialise.
Huddersfield head into the opening Sunday of the Premier League campaign on top of the table but manager David Wagner was under no illusions as to where they truly sit. Those 15 minutes in the first-half cost us and we were punished by a good Huddersfield team.
"Steve Mounie missed a big chance, we spoke about this rather than the two goals". But there is something memorable about the first round of league fixtures - and the 2016/17 Premier League delivered a thriller, as Liverpool beat Arsenal 4-3.
There was no sign of any nerves from Huddersfield right from the off at Selhurst Park, as they pressed the Eagles high and hurried them into mistakes. That included Chelsea and Manchester United loanees Ruben Loftus-Cheek and Timothy Fosu-Mensah, as well as Jairo Riedewald. "The Premier League is a great competition to be involved in and it is a great opportunity to be working under Frank de Boer once again having been with him at Ajax".
De Boer continued by saying: "We have to understand that the game doesn't last 75 minutes - it's maybe 95 or 98".
They created their first chance in the second minute, Tom Ince side-footing straight at Palace goalkeeper Wayne Hennessey after Patrick van Aanholt had inadvertently headed Tommy Smith's cross into his path. "We should focus on what we've seen today and what I've seen makes me very happy".
"It can not be a better day for a new striker in the Premier League", Wagner added.
If the answer is no you need to take a long, hard look at yourself.
The Ghana-eligible player, who was a second-half substitute, set up one goal as the visitors sealed the emphatic victory away from home.
