Scottish caveman, grand in crucial match? (6)
I believe the answer is:
fingal
'scottish caveman' is the definition.
'fingal' can be an answer for 'caveman' (I've seen this before). I am unsure of the 'scottish' bit.
'grand in crucial match?' is the wordplay.
'grand' becomes 'g' (G is short for grand as in a thousand).
'in' means one lot of letters goes inside another.
'crucial match?' becomes 'final' (final is a kind of match. I am not sure about the 'crucial' bit.).
'g' inserted within 'final' is 'FINGAL'.
Can you help me to learn more?
(Other definitions for fingal that I've seen before include "Caveman" , "Epic Scot" , "His cave is on Staffa" .)
