Where is the "frequently called numbers"-list on 4.4.4 (Sony Xperia Z1 compact)

I'm using a Sony Xperia Z1 compact. With an unmodified Sony 4.4.4 android.

On my dialer I see: 'contacts' 'call log' 'favorites' and 'groups'. Under favorite there are none (I didn't mark any). I want a "frequently called numbers"-list there, as I had on my old phone. I've been using this phone for two months now, so it should know who I usually call.
