The young Arsenal star reminds the Manchester United man of the former England international, whom he hopes can recover from his struggles with alcohol addiction
The 21-year-old Gunner caught the eye with a fine performance for England as they 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 realise," 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'."
