If Liverpool feel they have one more signing left in the tank, signing a midfielder linked to Arsenal all summer would be a spectacular coup.
Liverpool appear set to sign Italian international Mario Balotelli, yet should they try to acquire a World Cup winner to complete the side?
One player who looked off the pace in their 2-1 win over Southampton a week ago was Brazilian midfielder Lucas.
The 27-year-old defensive midfielder failed to win a single tackle against the Saints, and has been heavily linked with re-joining Rafa Benitez at Napoli.
For Liverpool they would have to replace him to sanction a sale, and that is why they should make a move for Real Madrid midfielder Sami Khedira.
Khedira has been linked strongly with a move to Arsenal all summer, but the Gunners are yet to make an offer for the player who featured heavily in Germany's World Cup run, injured in the warm-up ahead of the final.
He has only one year remaining on his current deal at Real Madrid, and despite Carlo Ancelotti's optimistic comments that he expects him to stay, it's likely the Champions League holders would cash in at the right price.
Khedira was left out of Madrid's UEFA Super Cup win over Sevilla, nor did he feature against Atletico Madrid in either leg of the Spanish Super Cup.
He is refusing to sign a new contract, and can leave on a free transfer next summer. Bayern Munich and Fiorentina have been linked, but Liverpool could steal a march on the competition by making the first offer.
Khedira is a star approaching his peak who has played at the highest level, and showed at the World Cup he has recovered from the knee injury which ruined his season in 2013/14.
Adding him to Liverpool's squad would seriously bolster their credentials for a push for honours on all fronts, add vital experience in shielding the defence, and free up the club's attacking talents to do their damage.
Would you like to see Liverpool go for Khedira? How much of a blow for Arsenal would it be if he signed?
