The former Sale Sharks scrum-half is relishing helping the Men in Black launch another Aviva Premiership title tilt next season while aiding his international ambitions with Martin Johnson's side.
Wigglesworth faces tough competition from Neil de Kock and Kevin Barrett for the number nine shirt ahead of the season opener with London Irish at Twickenham on September 4, yet the 27-year-old is unfazed.
He said: "There really is a special atmosphere and everyone is here to work hard and win, but there’s also a lot of enjoyment in the squad which makes it a great place to be. It was a massive decision to leave Sale Sharks. I’d been there for nine years, but Saracens is a club going places and I want to be part of it."
Wigglesworth admits he probably would have stayed at the Stockport club for as long as they wanted him had he not decided to take the plunge and move south, a decision he firmly believes has been the correct one.
"I just felt that if I hadn’t have left Sale at that point, I probably never would," he added. "I wanted to experience something different and come to the best club I possibly could. I want to challenge myself, hear new voices, win trophies and also enjoy myself along the way and Saracens ticked all those boxes."
The Blackpool-born star toured with England in the summer and is keen to push for further international honours.
He said: “There’s great competition in the squad at scrum half with Neil de Kock and Kevin Barrett and I want to challenge myself to be a better player - hopefully that will lead to more honours and me forcing my way back into an England shirt.”
