The 23-year-old joined the La Liga side from Arsenal in the summer for around £4m following a successful loan spell in Spain.
However, Vela has been linked with a return to the Emirates Stadium, with the Gunners believed to have a buy-back option on the Mexican.
"I'm calm and I'm not thinking about what will happen next season," he told Esta.
"If I worry it will be in June or July, and then I can speak about it. For now I'm just thinking of Real."
Vela has scored 11 goals in 24 appearances for Sociedad so far this season.
