Barcelona captain Lionel Messi could reportedly be in contention to feature in Wednesday's Champions League clash with Inter Milan at Camp Nou.
The Argentine has suffered an injury-hit start to the 2019-20 season and missed Saturday's 2-0 win over Getafe with an adductor injury which was initially expected to rule him out for up to three games.
However, Messi was back in training with the first team on Monday and could now be in the running to be included in the matchday squad against the Serie A leaders.
Ousmane Dembele also took part in the session, having suffered another injury setback of his own, missing the Getafe game due to a hamstring problem.
However, fellow attacker Ansu Fati remains sidelined while Jordi Alba is a major doubt and Samuel Umtiti is a longer-term absentee.
All four teams in Group F currently sit level on one point, with Barcelona holding Borussia Dortmund to a goalless stalemate on matchday one and Inter Milan only managing a 1-1 draw with Slavia Prague.
