The American keeper feels his time in the Far East turned out to be a 'lost summer' and was left frustrated on the sidelines after twice being told he was starting a game, only for the decision to be reversed.
"I'm too old for that stuff," reflected Kasey. "I was really happy when everything was over, put it that way.
"It was a big time lost summer, one in which I thought I'd aligned myself very well."
It is particularly evident that Kasey is delighted to be back at Spurs preparing for a new season after featuring in the final seven games of the last one. He wants to put his summer blues behind him and prepare to battle for the No.1 spot.
"Definitely. The season ended a little bit too soon for me. I got my chance, played in the last seven games and I thought that went pretty well.
"Now it's just a case of coming back and ensuring that those last seven games were the norm - what to expect.
"That's what I'm trying to do, come back and be fit and raring to go, have a couple of pre-season games and start right where I finished off."
Kasey admits he is not aware of who is in pole position for a starting spot when the season begins on August 17 at Everton.
"I don't know. I don't know if it's scratch or if I'm ahead or a little bit behind.
"You're asking the wrong person. I'm hoping that everything I did last year hasn't come to nothing. I fought real hard to get into the position I was in at the end of last season and I hope that just the summer hasn't erased everything.
"There's only one man that makes the decisions and we'll see what comes of that."
Kasey Keller says his World Cup disappointments make him all the more determined to pick up where he left off last season - in the Spurs starting X1.
