Mocks the German side in disarray (7)
I believe the answer is:
derides
'mocks' is the definition.
(deriding is a kind of mocking)
'the german side in disarray' is the wordplay.
'the german' becomes 'der' ('the' in German).
'in disarray' is an anagram indicator.
'side' is an anagram of 'ides'.
'der'+'ides'='DERIDES'
(Other definitions for derides that I've seen before include "Ridicules" , "Mocks, scorns" , "Laughs at" .)
