"Coming into a squad with a new look to it is exciting. There are plenty of players coming in at the moment, but there are also a number of guys here who have been at the club for a long time so I’m sure they’ll help lads like myself settle in, and right now I can’t wait to start getting involved.
"Everyone talks about how tough the league is and they’re right, you have to be at your best if you’re going to come out on top and with a lot of games to play it’s going to be really demanding on us this year."
FA Cup holders Wigan suffered relegation from the Premier League in May, with Coyle replacing Roberto Martinez after the Spaniard joined Everton.
