Assuming the newly observed structure $Z_{b}(10610)$ as a bottomonium-likemolecular state $B^{*}\bar{B}$, we calculate its mass in the framework of QCDsum rules. The numerical result is $10.54\pm0.22 GeV$ for $B^{*}\bar{B}$, whichcoincide with the mass of $Z_{b}(10610)$. This consolidates the statement madeby Belle Collaboration that the $Z_{b}(10610)$ resonance could be a$B^{*}\bar{B}$ molecular state.

Could $Z_{b}(10610)$ be a $B^{*}\bar{B}$ molecular state?
