Merseyside football club (7)
I believe the answer is:
everton
'merseyside football club' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for everton that I've seen before include "One side in blue" , "'The Toffees' FC" , "Merseyside football club" , "Liverpool football team" , "Liverpool football club" .)
