Gunter is now back in the Barclays Premier League after Reading boss Brian McDermott secured his services over the summer but the full-back will treat Sunday's fixture against Spurs the same as any other.
"I don't think you can go into games trying to prove people wrong or show people stuff," he said.
"I had a brilliant time at Tottenham, it is a great club and I learned so much there so I was really thankful.
"But I'm a Reading player now and I will be doing my best to focus on that and get three points on Sunday.
"It is the same as any game, especially in the Premier League. The fans have been brilliant so far and you would expect a full stadium for a game like Tottenham, it is a really big game but it is no bigger or smaller than any other game."
