Schumacher still unsure about Ferrari role

The German, who retired from racing at the end of last season, has attended several Grands Prix this year, although his role at the Italian squad is yet unclear to the general public.

Schumacher himself admitted he doesn't have a clear idea of how he will fit into Ferrari in the long-term.

"On that area, Ferrari and myself have not found a clear line yet," Schumacher said in an interview published in this week's journal of autosport.com. "But we do not see ourselves under pressure to finalise something.

"I have to admit that my knowledge is restricted by time. I would have to freshen it up constantly in order to be of help.

"I see many former drivers who try to comment on what is going on but they are struggling. They are simply no longer deep in the business anymore."

Schumacher, 38, says he is yet to find something that really motivates him after leaving Formula One.

"I really cannot say that have I found fresh challenges that would excite me so far," he said. "At Ferrari, there are constantly new opportunities coming up. But I could not pinpoint what exactly would be right for me.

"There is one thing I adore, however - helping to develop road cars. That is a lot of fun, and I believe that I can be of help (with that)."

The most successful driver in the sport's history says, however, that he is playing a part when he sits on the pit wall during the races this year.

"Now, that is something different. I am involved in certain discussions, I am in the briefings, I am aware of the details, and I can tell them what I think."
