Engineers think Nobel is out of order (2,3,5)
I believe the answer is:
on the blink
'out of order' is the definition.
(I've seen this before)
'engineers think nobel' is the wordplay.
'engineers' indicates an anagram (I've seen 'engineer' mean this).
'think'+'nobel'='thinknobel'
'thinknobel' with letters rearranged gives 'ON THE BLINK'.
'is' is the link.
(Other definitions for on the blink that I've seen before include "out of order" , "Not working properly" , "getting poor reception" .)
