Slonina, who arrived from MLS side Chicago Fire in the summer, started their international friendly match against Serbia last night.

Despite the European side winning 2-1 in Los Angeles, it was still a historic night for the 18-year-old.

Gaga wore the No.24 shirt and made six saves at the BMO Stadium.

Slonina has made one Chelsea appearance in the Premier League 2, which came earlier this month when we defeated Wolves 2-0.

Congratulations, Gaga!
