Liverpool legend Phil Thompson thinks Daniel Agger should play left wing-back in Brendan Rodgers's 3-5-2 formation.
The 28-year-old Danish international has made it clear he wants first-team football at Anfield, with reports claiming he could be tempted to leave if he fails to keep his place in the team.
And Thompson believes Rodgers should do everything in his power to keep Agger at the club, even changing his position if it comes to it.
"We need to make space for Daniel Agger," said Thompson as reported by the Daily Star.
The Reds defender has not started a Liverpool match since the 1-0 home defeat to Southampton, with Rodgers opting for Martin Skrtel, Mamadou Sakho and Kolo Toure in his three-at-the-back formation.
"He's played left-back and we're talking goals or assists here. He can play there, he can get goals. He's good in the air [and could be at] the far post like Alan Kennedy.
"When you've got a player of that ability, you have to find places to play these lads."
Rodgers changed to the new set-up following the failed four centre backs experiment against Southampton at Anfield.
The Liverpool boss started Sakho, Agger, Toure and Skrtel that day but the Reds were undone by a second half set-pice and lost the match 1-0.
Since then Rodgers has played three at the back with success, and Liverpool currently sit just two points off table toppers Arsenal.
But Agger's future is of concern to Thompson, especially considering the Danish defender was heavily linked with Barcelona over the summer.
