4. Daniel Agger
Barca have been linked with Denmark national captain Agger before. They may test the water again in January or June as the 28-year-old has hinted he may have to consider leaving Liverpool if he cannot win his place back in the XI. Reds boss Brendan Rodgers has switched to a back three, but summer signings Kolo Toure and Mamadou Sakho have got the nod alongside Martin Skrtel in recent matches. "I'm here to play football, nothing else,"
Agger told the Daily Express. "So if I don't play football, then I don't want to be here." If Barcelona can capture Agger they will add an experienced left-footed defender to their options at the back. As he is under contract at Liverpool until 2016, however, he will not come cheap.
