  Using integrability techniques, we compute four-point functions of single
trace gauge-invariant operators in N=4 SYM to leading order at weak coupling.
Our results are valid for operators of arbitrary size. In particular, we study
the limit in which two of the four operators are taken to be much smaller than
the others. We show that in this limit our weak coupling result matches with
the strong coupling result in the Frolov-Tseytlin limit.
