Liverpool have reportedly shown an interest in signing Fulham 19-year-old Fabio Carvalho. The Reds have already signed Luis Diaz in the January transfer window. The Deadline Day is almost over, however, if the Reds don't announce the youngster, they might sign him in the summer transfer window. After signing for the Reds, Diaz took number 23. So let's see which numbers are still available for Carvalho if he joins Jurgen Klopp's side. Carvalho current number is 28 at Fulham, which is currently occupied by Ben Davies, who is on loan at Sheffield United. No.2 is vacant as it was last worn by Nathaniel Clyne. Other numbers that are also available are 16, 19, 24, 25, 29, 30, and 31.
