King has been impressed with Parker and Adebayor and believes their arrival has freshened up a squad that was in danger of going stale.
"There was a lot of speculation pre-season, a lot of players not knowing whether they were coming or going so it was a little bit strange," King said.
"Scotty and Emmanuel have different qualities to the players we've let go, so it's something fresh.
"We needed to freshen up a little bit. We'd played with the same group of players for a while and it was important to bring some fresh faces in to give us something different."
With Parker and Adebayor in their ranks, King sees no reason why Spurs cannot regain the Champions League spot they lost last year.
"Having had the taste of it and doing so well in the tournament, the players felt like we belonged there so there is no reason why we shouldn't be striving for that again," he added.
