Gomez was a big player during his season loan with the Swans but has found the Premiership a tough task since his move to the Latics.
Speaking to WalesOnline.co.uk the Spaniard said: “It’s always difficult for a new team coming up, but they have a settled side and I think they can do well.
“A lot of great work has been done over the last two years and it’s great to be able to play against them now.
“When I was there, the aim was always to get into the Premier League within three or four years, and they’ve finally done it. I hope they will do very well this season, and I think that they will.
