Gray, 35, has proved a revelation at Hillsborough following his switch from Wolves on a free transfer in February, thriving in a more advanced midfield role afforded him by Owls manager Brian Laws.
Gray told his BBC online blog: "If one person inspires me to keep playing it has to be Ryan Giggs. He's a credit to his profession and a great role model to thousands (if not millions) - over 800 games for arguably the biggest club in the world and still playing at the top of his game.
"Maybe he doesn't play week in, week out, but every time I see Giggsy play he still has the desire to win. That is all down to Sir Alex Ferguson and how he manages his players.
"I remember Giggsy used to miss a lot of games because of hamstring injuries. When I spoke to him last he told me how he had changed what he did during a week's training and how he had recovered and if what he told me was good enough for him then it was certainly good enough for me - lots of ice baths during the week and after games, not the nicest thing in the world but very effective."
