The Terriers are preparing for their second campaign in the top flight, and Wagner has acted by making as many as nine first-team additions.
Wagner has revealed that he was keen to strengthen in attack and bring in players with more pace, and the German claims that he has been left delighted ahead of the new season.
At a press conference, the 46-year-old told reporters: "I'm very satisfied with what we've done and I'm now looking forward to working with this group of players.
"We wanted to strengthen our offence - there's no doubt about it after last season. We wanted to have a little bit more pace in our squad as well and I think with our signings, especially in the offence, we've done this. I'm very happy with all of our signings."
