The 21-year-old Gunner caught the eye with a fine performance for England as the Three Lions beat Brazil in midweek and the United forward sees similarities with the former Tottenham player, who is struggling with alcohol addiction.
"The way [Gascoigne] ran with the ball... probably the closest thing I've seen to him is Jack, where he gets the ball and runs at players a lot quicker and a lot stronger than people realize," Rooney told reporters. "It's great to see such a young player come in, against a team like Brazil, and put in a performance like that."
Gascoigne flew to the United States in early February after suffering a relapse, with his agent, Terry Baker, remarking that he needs "immediate help", and Rooney hopes that the Three Lions icon can recover.
"It's a terrible shame about Gazza," the United star lamented. "My best wishes are with him and I hope he can get himself out of this. He was a hero of mine and I used to dream of being like him. It's so sad for everyone to see what's happening to him.
"I got to train with him when I was a kid [at Everton]," he enthused. "It was only a couple of times, when I was 14 or 15, I had watched him playing for England for years and to then have him where I was training was great.
"To see the stuff he could do with a ball was brilliant. It was a great experience for me. I used to go home and tell my mates, 'I've just trained with Paul Gascoigne.'"
