Brendan Rodgers realistically has five central defenders fighting for two spots in the side for the trip to the Liberty Stadium.
The Anfield side are yet to concede a goal in three Premier League games, and travel to take on Swansea at the Liberty Stadium tonight. However, the Northern Irish manager has decisions to make regarding his first-choice centre-half pairing.
Daniel Agger has been an ever-present this season so far, and you would assume that the talented Dane will play whenever fit and available. Realistically, that only leaves one spot for four other players to battle it out for.
Rodgers has spoken of protecting the Liverpool defence for a decade with his new signings, and weighed up their chances of playing tonight.
“I wanted to try and protect the present and the future of the club," Rodgers said.
"Good centre-halves are so hard to find. You look at some teams and they have ageing centre-halves because it is a struggle to get a really good one.
"We were fortunate in that two became available. One we had been tracking for a year in Tiago Ilori, a young talent who can be a big talent. He is 6ft 3in, super quick, powerful, can jump. He just needs to adapt to the pace and physicality of the Premier League. He is one for the future but he can be a really big talent.
"Sakho is 23 but he is an experienced player, he has senior international caps and looks an absolute monster in training. He is one who is ready for now and that is what we want. We had a chance to protect the club for maybe the next 10 years and that is what we have done."
Even without the acquisition of the two new players, Rodgers would have had a selection dilemma on his hands.
Kolo Toure, who moved to Anfield from Manchester City over the summer, has started life at Liverpool well and has looked accomplished in his appearances for the club so far. With the Ivorian back from a niggling injury, he will look to win his place in the side back.
Martin Skrtel played for the Reds against Manchester United and did a fantastic marking job on Robin van Persie. Given this impressive showing you would expect the Slovakian enforcer to continue playing, but it remains to be seen whether he will or not.
It is worth considering that both Agger and Sakho are left footed, and it is rare to see two left footed centre backs partnered together. Toure has the experience and Skrtel is in form – so who should Rodgers pick for the clash with Swansea?
