Put faith in Len and Roy striving together (4,2)
I believe the answer is:
rely on
'put' is the definition.
The answer and definition can be both related to thinking as well as being verbs in their base form.

I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for rely on that I've seen before include "Trust, be confident in" , "Trust in with confidence" , "Put trust in" .)
