Tries seen in international matches (5)
I believe the answer is:
tests
I believe this clue is a double definition.
'tries' is the first definition.
(test is a kind of try)
'international matches' is the second definition.
(I've seen this before)
'seen in' is the link.
(Other definitions for tests that I've seen before include "International cricket matches" , "Trials, exams" , "Trials to see if something works" , "Trials for cricketers" , "Major cricket matches" .)
