Hearts defender Marius Zaliukas has questioned the appointment of Christophe Berra as the club's new captain.

"In my opinion he is a little bit too young," says the former Kaunas player. "All the time in training he is talking and wanting to help and he is mature but Robbie [Neilson] is the older player in the team. I think he would be a better captain but it's not my decision."
