Latics manager delighted at Swans' rise to English top tier and cannot wait for "great occasion" when the sides meet, and hopes former club's fans will show respect for his efforts
Martinez took the Swans to the Championship during his time in Wales and has spoke of his pride that the club have continued their progression and have now returned to the peak of the English game.
Martinez eventually left the club to join Wigan in the Premier League, and faces his former club for the first time on Saturday.
"I'm really proud of what was achieved in my time at Swansea, and it will be an emotional return for me," Martinez told reporters.
"I hope that even if they don't show it, the Swansea fans respect the job I did when I was there.
"We got the club moving in the right direction, and in view of the fact that Swansea gained promotion to the Premier League after I'd gone, I don't think anyone can say my decision to leave was such a bad one."
Whilst Martinez is proud of his own personal contribution to the club's efforts, he has also been quick to point out that current manager Brendan Rodgers must take the credit for their promotion last season.
"I can't take any credit for getting Swansea into the Premier League, that's all down to Brendan Rodgers," Martinez added.
"But I think you could see at Manchester City the other day that Swansea still play with a lot of confidence. Not many other teams will go to Eastlands and put 500 passes together.
"They will certainly be a tough proposition for anyone at home, and from a footballing point of view I could think of better times for Wigan to be playing them."
