West Ham legend Hurst: Arsenal midfielder Wilshere invites injury problems
Sir Geoff does not want to see the 21-year-old's all-action style cost him more game time.
The World Cup winner told The Sun: "I do feel sometimes that because he's such a wholehearted and aggressive player, who does fantastically well for Arsenal, that he goes into tackles a little naively and leaves himself open to get hurt.
"Having another injury so close to the previous problems, you start to be a little bit concerned about his professional future.
"There are certain players - and I'm not sure if you can say this in Jack's case - who seem to be injury-prone."
