Stimulated by the observation of the newly X(3960) observed by the LHCb collaboration, we adopt the one-boson-exchange model and consider the S-D wave mixing effects to study the DsDs/D^*D^*/Ds^*Ds^* interactions with I(JPC)=0(0++). After producing the phase shifts of this coupled channel systems, our results show that there can exist a charmoniumlike resonance, whose obtained mass and width can both well match with the experimental data of the newly observed X(3960). We also find that the D^*D^* system plays an important role in the formation of the newly observed X(3960) as a charmoniumlike resonance, and the Ds^*Ds^* system makes a significant contribution to the resonant width. As a byproduct, we perform a coupled channel analysis on the D^*D^*/DsDs^*/Ds^*Ds^* interactions with I(JPC)=0(1+-), our results can predict the existence of the DsDs^* molecule with 1+- and the Ds^*Ds^* molecule with 1+-. Their widths are around several and several to several tens MeV, respectively. Experimental searches for these two possible charmoniumlike molecular candidates can be helpful to verify our proposal.
