DE BRUYNE 17 Manchester City 16/17 Soccer Jersey Men's Home Color Blue Size M

Things looks good but i have one doubt here.In lower logo where it is written Authentic and some number, the year written is 2017. I bought one away jersey from Man City shop this year and it has been written Authentic 2016 on it. If this Jersey is for 2016/17 season then why it has been written Authentic 2017? Please clarify this else rest looks good.
