Ciao Umberto, AFAIK, classification is multivariate on its statistical basis, so that's why it will only take a group as input. If you only have one band, you may want to extract some information from it, for example by using r.texture module [1]. With those resulting new bands and the original one you can create then a group and perform the classification you prefer.
HTH!
