WATCH: Messi scores first goal as Barcelona captain
The Argentina attacker is reportedly considering retiring from international duty for the second time after a disappointing World Cup campaign.
But Messi appeared happy and relaxed when making his first appearance of 2018-19, with Barca facing Boca Juniors in the Joan Gamper Trophy at Camp Nou.
Malcom had already given Ernesto Valverde's men the lead in Wednesday's contest when Messi made his mark with a superb lob after an inadvertent one-two played with a defender.
