Brendan Rodgers' Liverpool have made a more-than-respectable start to the new season, losing just once in their opening nine matches and having most recently put a decent West Brom side to the sword with a mightily impressive 4-1 victory.
And under the former Swansea boss, improvements continue to be made and the Reds—whisper it quietly—are certainly in the hunt for a top-four place come the end of the season.
Nonetheless, for all their strengths—the strike partnership, the depth at centre-back, Philippe Coutinho, tactical flexibility—there do remain some issues that need ironing out.
Despite the loan signing of Victor Moses, they still miss an outstanding wide player to play in high areas of the field when Rodgers selects to go away from using wing-backs.
Most importantly perhaps however is the need for a new central midfielder. Certainly Steven Gerrard and Lucas have been doing a stand-up job—aided by the hard-running Jordan Henderson—and Joe Allen (when fit) offers a good option as a deep-lying playmaker given his metronomic passing, but there remain times when they are just too easy to play through.
In their only league defeat, Southampton's Victor Wanyama constantly ate up ground with direct, striding runs through central areas. In the games against Swansea, Aston Villa and for a period at Sunderland, it has also been noticeable how when the midfield retreats closer to its own goal, it has struggled to get close to opponents and break up play before springing through the middle.
As such, a powerful, tenacious, talented central midfielder—someone who matches the energy of Henderson, with the kind of physical dominance of Yaya Toure—would be quite the addition to Rodgers' outfit.
With that in mind, here's a look at five players—and let's not kid ourselves: Ilkay Gundogan, Javi Martinez and players of that ilk will not be trading in potential Champions League winners for a move to Anfield—who Liverpool would do well to consider in January.
