#2 Steven N'Zonzi
For a Liverpool side mostly made up of flair players, Steven N'zonzi's height and strength would be a much-welcomed addition to the Merseysiders' midfield and a potential upgrade on Can.
The Sevilla player has been consistently linked with a move to Arsenal and his side's manager Vincenzo Montella recently added fuel to that fire by admitting he wasn't confident the Frenchman would remain in Spain beyond the winter transfer window.
That could provide an opportunity for Liverpool to join their rivals in the race for N'Zonzi either this month or at the end of the season.
The former Stoke City man plays primarily as a defensive midfielder and would provide good cover for Liverpool's back four, allowing the forward players to freely attack their opponents. N'Zonzi's passing and aerial ability would also add another potential threat in attacking situations, mainly set-pieces.
