The best side of a club (5,6)

Ross

I believe the answer is:

first eleven

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

'a club' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'the best side' is the wordplay.
'the best' becomes 'first' (the top).
'side' becomes 'eleven' (I've seen this before).
'first'+'eleven'='FIRST ELEVEN'

'of' acts as a link.

Can you help me to learn more?
