He represented the under-21 team at the 2015 European Championship in the Czech Republic, starting all four matches. In their opening game at the Letná Stadium in Prague on 17 June, Can scored with a 17th-minute equaliser from the edge of the penalty area in a 1–1 draw against Serbia. In their second group match at the Eden Arena in Prague against Denmark on 20 June, Can hit a slide-rule pass to assist Kevin Volland's smart finish in the 32nd minute. In the 47th minute Can was awarded a free-kick, from which Volland doubled the lead thanks to a delightfully weighted free-kick from 25 metres out. Matthias Ginter rounded off the scoring to head in Amin Younes' cross just five minutes later leading to a 3–0 victory. Germany were eliminated in the semi-finals following a 5–0 defeat to Portugal on 27 June, in which Can started.
