Michael Schumacher’s management have again called for an end to the speculation regarding the condition of the seven-time Formula One world champion.

It is exactly one month since Schumacher was involved in a skiing accident at the French resort of Meribel that resulted in him requiring surgery to remove blood clots from his brain.

The 45-year-old has since been in an artificially-induced coma at the University of Grenoble hospital.

Given the length of time Schumacher has remained in such a condition, that has resulted in many reports commenting on whether he will ever make a full recovery, or even if he will wake up again.

Such rumours have intensified given the fact Schumacher has now been in a coma for one month.

That has resulted in Schumacher’s manager, Sabine Kehm, urging fans to ignore the hype and gossip.

Kehm said: “I am stressing again any statement regarding Michael’s health not coming from the doctors, or from his management, must be considered as speculation.

“I repeat, we will not comment on any speculation.”

On Tuesday, on the first day of pre-season testing in Jerez, Schumacher’s friend and compatriot Sebastian Vettel revealed he is still praying for a miracle.

Vettel said: “He’s still in a coma and we still don’t know what shape he will be in when he wakes up, which is horrible, especially for his family and close friends, not knowing what is going to happen

“I’m still as shocked as everybody else, and I pray and hope the miracle will happen, he will come back and be the person he was before.”

The Mercedes car being driven by Lewis Hamilton and Nico Rosberg this week is carrying the message ‘#KeepFightingMichael’.
