During Owen's five years at Newcastle he often had the Toon medics baffled, but Gunners manager Wenger is confident Fabregas is not in the same boat.
Arsene Wenger: "Cesc is a ball giver and Owen was more a runner.
"The strength of Owen was more based on his pace and the timing of his runs.
"Cesc is more a playmaker, so he doesn't need to sprint as much.
"That's what is remarkable in Cesc's case: usually, people who are exposed to hamstring injuries are sprinters like Owen or Ryan Giggs but Cesc is more a stamina player and that's what puzzles me a little bit.
"I'll do what is right for him and for the club but I will listen, of course, to medical people.
"It is a hamstring and I remember Ryan Giggs has gone through that his whole career but it didn't stop him from making a big career."
