Maybe Labour, and its old leader Miliband, like Messi? (4-6)

'messi?' is the definition.
I can't tell whether this defines the answer.

'maybe labour and its old leader miliband' is the wordplay.
I cannot quite see how this works, but
'labour' could be 'left' (I've seen this in other clues) and 'left' is found in the answer.
'old' could be 'o' (abbreviation) and 'o' is found within the answer.
'leader' could be 'f' (I have seen 'German leader ' mean 'f' so perhaps 'leader' could also mean 'f') and 'f' is found in the answer.
'miliband' could be 'ed' (politician Ed Miliband) and 'ed' is found in the answer.
The remaining letters 'ot' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'like' is the link.

Can you help me to learn more?
