Gladwin has joined Swindon on a month-long loan spell, having only left the club in a big-money transfer deal over the summer.
And Power has been delighted to welcome the attacking midfielder back to the County Ground, after collecting so much money for him during the previous transfer window.
“It’s the best bit of business in the world," Power said. "We sold him for £3million and then got him back on loan three months later.
“You can see how he makes the team tick. In the first half [against Coventry], he was unfortunate. He found himself in those little pockets and you’re waiting for him to go on and, for whatever reason, the ball didn’t run for him."
Gladwin's loan is set to expire at Swindon after their match against Wigan Athletic at the weekend, but Power, who is currently managing the side on a temporary basis, has confirmed that he would like to extend the attacking midfielder's stay.
Whether QPR will sanction such a deal remains to be seen, as Gladwin has shown his class during his loan spell with the Robins.
Although Swindon's form has not been particularly impressive, Gladwin's quality has stood out in every match he has played, and he scored a wonderful goal against Coventry in their latest outing.
If the 23-year-old does return to QPR, he will hope that Chris Ramsey gives him more opportunities to impress, as he has made just three appearances for the London side to date.
