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

'don't be impartial' is the definition.
I can't tell whether this defines the answer.

'consider the teams' is the wordplay.
'consider' becomes 'take' (synonyms).
'the teams' becomes 'sides' (eg football sides).
'take'+'sides'='TAKE SIDES'

'but' acts as a link.

Can you help me to learn more?

(Other definitions for take sides that I've seen before include "Come off the fence?" , "choose who to support" , "Prefer a party" , "Be partisan, support one party" , "Support one faction" .)

I've seen this clue in The Irish News.
