He was then called up to multiple fixtures but had to wait for his competitive debut until 1 September 2017, for a 2018 FIFA World Cup qualifier against Slovenia. He played the entire match being a valuable midfielder, fulfilling the expectations following the successful performances of Lobotka and Slovakia U21 at the 2017 UEFA European Under-21 Championship, as well as his move to Celta Vigo. His performance contributed to Slovakia's 1-0 home win and he was dubbed the 'Man of The Match' by media and the fans.
