The Argentine has been out of action since Nov. 10 but is now in contention to feature in Sunday's Liga clash with Elche at Camp Nou.
Barcelona has confirmed that Lionel Messi has returned to training after more than a month out with a hamstring problem.
The 26-year-old suffered the injury in the 4-1 Liga victory over Real Betis on Nov. 10 and returned to his native Argentina for treatment.
However, Barcelona announced on Thursday that not only is Messi back in Catalunya, the forward is also back in action.
"Leo Messi landed in Barcelona this afternoon and went directly to the Ciutat Esportiva to meet up with his teammates and get fitted for new boots ahead of the team’s training session," read a statement on the club's official website.
"Messi, who has yet to be declared match fit, took part in the team’s second training session of the day."
Barcelona, which tops La Liga on goal difference over Atletico Madrid, resumes its bid for a second successive Spanish title when it faces Elche at Camp Nou on Sunday.
