Match at home provides link (3-2)
I believe the answer is:
tie-in
'link' is the definition.
(synonyms)
'match at home' is the wordplay.
'match' becomes 'tie' (tie can mean a sporting fixture).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'tie'+'in'='TIE-IN'
'provides' acts as a link.
(Other definitions for tie-in that I've seen before include "Make a link (with)" , "Book linked to TV or film production" , "Item linked with popular film, programme etc" , "Coordinate" , "Book, etc, linked to film, TV show" .)
