Liverpool manager Brendan Rodgers has admitted that having several quality centre-backs at the club is a "nice problem".
The Reds added to their defensive stock when they secured the signings of Mamadou Sakho and Tiago Ilori on transfer deadline day.
Rodgers told reporters: "It's a nice problem to have. I would rather this than have a lack of talent to choose from. It just keeps everyone on their toes.
"Sakho is 23; he's an experienced player with full international caps and looks an absolute monster in training. He's one who's ready for now. That's what we want.
"It's not so much a problem [trying to get him in the team]. If you are winning games, it's very simple. The system is king. We will never be reliant on one player."
Liverpool face Swansea City later today.
