Lamela is impressing for Roma this season.
"I was close to joining Barcelona, but I don't regret that, as I don't know what would've happened there," 'Coco' Lamela told ESPN Radio.
"If I am to play for Argentina, then it's up to me, as I must continue performing well to get an opportunity.
"Fortunately things are going well for me. The key is to train consistently and put yourself on show with a great club side."
