The prolific 26-year-old attacker is raring to go again after missing his side's last two games due to a thigh problem, and is set to be fit for Saturday's trip to Osasuna
The Argentina international was unavailable for the Champions League defeat of Celtic and the Liga win over Real Valladolid because of a thigh strain sustained in last month's trip to Almeria, while he was also absent for his country's World Cup qualifiers with Peru and Uruguay.
However, the 26-year-old attacker resumed full training earlier this week and is now ready to make his Blaugrana return in Pamplona.
"Ready to come back," Messi wrote next to a picture of him training on his Instagram account.
The four-time Ballon d'Or winner has made nine appearances in all competitions for Barca this term, scoring 11 goals.
