According to reports from England, a timeframe has not yet been given for the return of Thomas Partey into the side.
The 27-year-old had to be substituted during Arsenal's clash against Tottenham due to a reported thigh injury.
The coach was asked about the injury and he stated that he will be out for the next 'few games'.
In Arsenal's medical report ahead of the game against Southampton, it stated that Partey will be out for the 'forthcoming matches' with no specification of a possible arrival date.
It is however believed by other reporters that the Ghanaian will be back in January.
Partey signed for the Gunners during the 2020 summer transfer window.
