Cattermole is looking forward to revisiting his former employers this Saturday after missing last season's game through injury.
"I've not been back there yet but Wigan was a great club for me," Cattermole, who will join Titus Bramble in heading back to the Lancashire club, told safc.com.
"They were a great stepping stone in between Middlesbrough and here. Everyone at the club was brilliant, from the chairman down. Obviously the manager and the staff came here.
"I loved my time there and I have a lot to respect them for."
