I believe the answer is:

superbowl

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

'championship game' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'excellent winger' is the wordplay.
'excellent' becomes 'superb' (I've seen this before).
'winger' becomes 'owl' (owl is a kind of bird).
'superb'+'owl'='SUPERBOWL'

'makes' is the link.

Can you help me to learn more?

(Other definitions for superbowl that I've seen before include "sporting event" , "American competition?" , "big game in America" .)

I've seen this clue in The Sun.
