Argentine team's beef — bit near bone (10)
I believe the answer is:
silverside
'beef bit near bone' is the definition.
'silverside' can be an answer for 'beef' (I've seen this before). I am not certain of the 'bit near bone' bit.
'argentine team's' is the wordplay.
'argentine' becomes 'silver' (I can't explain this - if you can you should give a lot more credence to this answer).
'team' becomes 'side' (both can mean a sports team).
'silver'+'side'='SILVERSIDE'
Can you help me to learn more?
(Other definitions for silverside that I've seen before include "piece of meat" , "Cut of meat" , "Joint" , "Crown of a round of beef cut from the leg" .)
