Messi: I'll finish career at Barca
Messi returned to Spain last week after completing the last stages of his recovery from a thigh operation in Argentina.
And he was back in action on Wednesday night, replacing Andres Iniesta in the 64th minute before finding the net twice in his side's 4-0 victory.
While the 26-year-old is synonymous with Barca, having joined the club in 2000, he has been linked with Paris St-Germain.
However, he was unequivocal with regard to his future, saying: "I would like to finish my career at Barcelona."
Wednesday night's match was his first since he injured his hamstring in early November and he was pleased with his progress.
He said: "I took a long time away, I felt very well in training and I'm slowly feeling better.
"I went to Argentina with the intention of returning here at the beginning of the year and returning slowly to the team.
"I felt good physically, I didn't feel any pain in the hamstring. I was very happy to be in my country. I worked well to get out of this. Now I'm looking forward to a great year."
Barcelona's next game sees them pitted against Atletico Madrid, who are second in the Primera Division on goal difference.
Messi was unsure of the extent of his involvement, saying: "We'll talk to Tata (Gerardo Martino, Barcelona coach) and the medical staff to see what is decided for the next game.
"I always want to be on the field. I always want to help my team."
