Notes teams as well (7)
I believe the answer is:
besides
'as well' is the definition.
(both can mean 'in addition')
'notes teams' is the wordplay.
'notes' becomes 'be'.
'teams' becomes 'sides' (eg football sides).
'be'+'sides'='BESIDES'
(Other definitions for besides that I've seen before include "to boot" , "In addition, as well" , "Apart from" , "See bids (anag)" , "Moreover" .)
