Metal vehicle carrying goods for street at one end of sports ground (8)

'metal' is the definition.
(vanadium is a kind of metal)

'vehicle carrying goods for street at one end of sports ground' is the wordplay.
I cannot quite understand how this works, but
'vehicle' could be 'van' (van is a kind of vehicle) and 'van' is found within the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
This may be the basis of clue (or it may be nonsense).
