Football club has rushed in European currency (5)
I believe the answer is:
franc
'european currency' is the definition.
'franc' can be an answer for 'currency' (old French currency). I am not sure about the 'european' bit.
'football club has rushed' is the wordplay.
'football club' becomes 'FC'.
'has' means one lot of letters goes inside another.
'rushed' becomes 'ran'.
'fc' enclosing 'ran' is 'FRANC'.
'in' is the link.
Can you help me to learn more?
(Other definitions for franc that I've seen before include "Foreign capital" , "Old French money" , "Old European currency" , "Foreign currency" , "Former French monetary unit" .)
