Moses signed a three-and-a-half-year contract at the DW Stadium after passing a medical at the club over the weekend. The powerful forward admitted he was sad to leave Palace but said he was looking forward to the challenge of playing top flight football.
"To play in the Premier League is a dream and I want to thank Roberto Martinez and Wigan for giving me the chance to do that," Moses said.
"I'm sad to leave Palace because they're a great club and gave me my chance in football and I want to say thanks to everyone there.
"But I need to prove myself now at Wigan and I'm going to focus on getting in the team and doing well for my new club."
