Marco Verratti stepped up his recovery from a thigh injury by returning to training with Paris Saint-Germain on Wednesday.
The midfielder returned from international duty in October with the issue and has missed the past seven matches in all competitions.
It will be a boost for PSG boss Thomas Tuchel, who has been contending with a raft of injuries to key players this season.
Verratti performed light, individual exercises and Mauro Icardi is expected to follow suit this week.
PSG have won all five of their Ligue 1 games without Verratti this season, with the Italy midfielder in the line-up for their two defeats at the start of the season.
Among all players to feature in at least 10 Ligue 1 matches last season, only Leandro Paredes attempted and completed more passes than Verratti per 90 minutes.
