Mikel Arteta tweaked Arsenal's midfield setup at the start of the season with Thomas Partey acting as a lone holding midfielder. The Ghana international has proved to be one of the best players in the team this term but there are concerns that if he was to be injured it could derail the Gunners' title charge.
Arteta wanted to add a new midfielder to his squad back in the summer when both Partey and Mohamed Elneny were injured heading into September. A deal for Douglas Luiz from Aston Villa failed to go through but the Ghanaian was back fully fit in just a matter of days, easing the impact on Arteta's squad.
Elneny is now set to miss a significant amount of time through injury again which saw Arsenal sign Jorginho in a £12million deal from Chelsea. Partey is a completely different player to the Italian midfielder but should the 29-year-old suffer an injury, at least Arteta has capable replacement to call upon.
