Like the stars in the team - the Madrid team (8)
I believe the answer is:
sidereal
'like the stars' is the definition.
I can't tell whether this definition defines the answer.
'team the madrid team' is the wordplay.
'team' becomes 'side' (both can mean a sports team).
'the madrid team' becomes 'Real' (Real Madrid football club).
'side'+'real'='SIDEREAL'
'in the' is the link.
Can you help me to learn more?
(Other definitions for sidereal that I've seen before include "involving stars" , "Full of stars" , "Of or measured by the stars" , "Of the stars or constellations" , "Realised (anag) -- relating to the stars" .)
