Keep an eye on love poetry by European (7)
I believe the answer is:
oversee
'keep an eye on' is the definition.
(thesaurus)
'love poetry by european' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'poetry' becomes 'verse' ('verse' can be a synonym of 'poetry'**).
'by' says to put letters next to each other.
'european' becomes 'e' (abbreviation e.g. EU).
'o'+'verse'+'e'='OVERSEE'
(Other definitions for oversee that I've seen before include "Exercise supervision" , "Keep an eye on like foreman" , "Disregard" , "Supervise, monitor" , "survey" .)
