Football's premier league's travelling in this part of the plane (8)
I believe the answer is:
fuselage
'this part of the plane' is the definition.
('fuselage' is part of 'plane')
'football's premier league's travelling' is the wordplay.
'premier' suggests taking the first letters.
'travelling' is an anagram indicator.
The initial letter of 'footballs' is 'f'.
'leagues' with letters rearranged gives 'uselage'.
'f'+'uselage'='FUSELAGE'
'in' is the link.
(Other definitions for fuselage that I've seen before include "Long body" , "Body of plane" , "body of fighter?" , "Central body of an aeroplane" , "part of plane" .)
