Let 
$G$
be a compact group. The aim of this note is to show that the only continuous *-homomorphism from 
$L^{1}(G)$
to 
$\ell ^{\infty }\text{-}\bigoplus _{[{\it\pi}]\in {\hat{G}}}{\mathcal{B}}_{2}({\mathcal{H}}_{{\it\pi}})$
that transforms a convolution product into a pointwise product is, essentially, a Fourier transform. A similar result is also deduced for maps from 
$L^{2}(G)$
to 
$\ell ^{2}\text{-}\bigoplus _{[{\it\pi}]\in {\hat{G}}}{\mathcal{B}}_{2}({\mathcal{H}}_{{\it\pi}})$
.
