This is perhaps further illustrated at the weekend when Liverpool threw away a two-goal lead to Southampton after Lovren was replaced by Martin Skrtel at half-time, with the Reds going on to lose the game 3-2. Aldridge's case is probably strengthened further by the damning statistic that was doing the rounds on twitter following Liverpool's loss to the Saints.
Lovren and Sakho have shown signs of good form over the past few months, while experienced centre-back Kolo Toure has also had a role to play when the defence has looked its most solid, while the Slovakian's return to the side was nothing hosrt of terrible.

40 minutes with Martin Skrtel = 3 goals conceded.
Aldridge wrote in his Liverpool Echo column: "It’s obvious from what we’ve seen that Mamadou Sakho and Dejan Lovren are our best pairing at centre back. They had one or two hairy moments but that happens to everybody.
"It’s all about partnerships and being able to read each other’s game and we can see that starting to grow."
As for the situation on Sunday, Aldridge added: "Hindsight is a wonderful thing in football.
"But I think Kolo Toure certainly has a strong argument for the fact it should have been him coming on. I think among Liverpool’s squad players Kolo has been excellent this season.
"He’s been class in the dressing room, in the Merseyside area when he’s been representing the club as an ambassador and he’s never let us down when he’s played."
