Kindly stop vandalising. 

What you had done repeatedly with family names Alempijević et al. is vandalising. As per Category:Redirects_from_surnames redirect "MAY be used" if there is only one person with that surname but only if s/he is well known under the surname alone. And even then it does NOT HAVE to be used. In the case of football players, they are certainly not famous enough (and neither is some minor politician being tried) to be considered an exclusive representative of the surname.

Family name is a separate entry from these individual people. Family names in various languages do have separate entries. Maybe the article about Ćesarević and Alempijević needs expounding to be a decent article on a family name, but it most certainly does not need to be vandalised with effacing it and redirecting, it is a valid entry as such.
