We may lose after performing really well (9)

Ross

I believe the answer is:

awesomely

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

'really well' is the definition.
The definition suggests an adverb which matches the answer.

'we may lose after performing' is the wordplay.
'after performing' is an anagram indicator.
'we'+'may'+'lose'='wemaylose'
'wemaylose' anagrammed gives 'AWESOMELY'.

Can you help me to learn more?

(Another definition for awesomely that I've seen is " impressively".)

I've seen this clue in The Telegraph.
