Liverpool boss Brendan Rodgers admits he has a central defensive dilemma.
Rodgers is struggling to fill the void left by Jamie Carragher's retirement.
"It's probably the first job I have been in where there have been lots of areas I have been happy and settled in but this (central defence) is an important area," said Rodgers, whose side face Norwich tonight at Anfield.
"It's something I need to look at in order to get that consistency. There has been lots of change - and some of that has been down to me - knowing every game is an absolute cup final for us. If I feel I have need to change it going into a game to get a result, then I will do.
"But of course I also need to look at it from the coaching perspective as well, that a little run in the team might breed the consistency even though we have had to change a number of positions."
