Liverpool's preparations for Sunday's match against title rivals Manchester City have improved because of Daniel Agger's return.
The Dane missed last weekend's controversial 2-1 win against West Ham, with Mamadou Sakho replacing Liverpool's vice-captain.
Agger, who joined Liverpool in 2006, has played 230 times for the Reds, including a Champions League and Capital One Cup final.
His big-match experience will benefit Brendan Rodgers' side against City, who have a wealth of attacking talent.
Sergio Aguero, Edin Dzeko and Alvaro Negredo have scored 79 goals between them in Manuel Pellegrini's first year in English football.
Stefan Jovetic is another talented forward Agger may have to stop, as the central defender plays his most important Premier League game for the club.
Martin Skrtel and Agger will have to keep their concentration throughout as one lapse could result in the crafty David Silva punishing them with a perfectly-weighted pass.
In the reverse fixture at the Etihad on Boxing Day, Liverpool lost 2-1 after Phillippe Coutinho gave them the lead and they cannot afford to repeat this with just five games left.
