Team consumed by anger over magic potion (6)
I believe the answer is:
elixir
'magic potion' is the definition.
(I've seen this in another clue)
'team consumed by anger over' is the wordplay.
'team' becomes 'XI' (a football team, from Roman numerals for rr).
'consumed by' is an insertion indicator (inserted letters get consumed).
'anger' becomes 'rile' (rile can mean to annoy or anger).
'over' is a reversal indicator.
'xi' put within 'rile' is 'rixile'.
'rixile' in reverse letter order is 'ELIXIR'.
(Other definitions for elixir that I've seen before include "Substance that alchemists believed could turn base metals into gold" , "The old alchemists sought this of life" , "Potion, panacea" , "Miraculous cure" , "Sweet-tasting potion" .)
