I believe the answer is:

racer

I'm a little stuck... Click here to teach me more about this clue!

'f1 man?' is the definition.
I can't tell whether this definition defines the answer.

'champion in rolls-royce' is the wordplay.
'champion' becomes 'ace' (both can mean a person excelling at something).
'in' indicates putting letters inside.
'rolls royce' becomes 'rr' (short for Rolls Royce).
'ace' going inside 'rr' is 'RACER'.

Can you help me to learn more?

(Other definitions for racer that I've seen before include "Perhaps 16 [SCRAMBLER]" , "Greyhound" , "Fast competitive car or animal" , "American snake" , "Runner" .)

I've seen this clue in The Sun.
