Greek character returning with lots of footballers, clears the luggage (7)
I believe the answer is:
unpacks
'footballers clears the luggage' is the definition.
I can't judge whether this definition defines the answer.
'greek character returning with lots' is the wordplay.
'greek character' becomes 'nu' (letter from the Greek alphabet).
'returning' is a reversal indicator.
'with' means one lot of letters go next to another.
'lots' becomes 'packs' (pack is a kind of lot).
'nu' reversed gives 'un'.
'un'+'packs'='UNPACKS'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for unpacks that I've seen before include "after the holidays?" , "Opens gifts" .)
