Villa hasn't featured for his country since the summer of 2014 and had flirted with international retirement in the ensuing period.
"I'm living on cloud nine seeing all of my friends and teammates and recalling all of the great memories but I'm also living in the present," Villa told reporters.
"My role, as always, will be to help the team win and put all that I have into benefiting the national team. The coach is the one who decides if I will play but I'll give everything to help.
"For me, it won't be a disappointment if I don't play though. Whatever is decided, I'll be supporting the team to the fullest."
