TORONTO, June 20 (Reuters) - ⁠Germany coach Julian Nagelsmann said his team's 2-1 comeback victory ⁠over Ivory Coast on Saturday was deserved as the nation secured ‌their first World Cup knockout-stage berth since they won the title in 2014.

"I am very happy that we won the match. In the end, we deservedly won it," Nagelsmann ​told reporters via a translator in Toronto, describing ⁠the win as emotional.

"The boys ⁠invested a lot. I'm very happy for the whole team because everyone knew ⁠they (were) ‌important. Every player that came into the match (was) important."

Substitute Deniz Undav was Germany's hero on the day, scoring two goals in ⁠the second half to erase Ivory Coast's lead and ​fire Germany into ‌the knockout stage.

"When (the game) opens up he's really great at moving ⁠around," Nagelsmann said ​of Undav, adding that the forward's performance could possibly earn him a start in the team's final group-stage match against Ecuador. "Deniz is nobody who needs to ⁠be prepared; he can jump in right ​away."

Nagelsmann said his side did not have enough control at the beginning of the game. He was not satisfied with the first 10 minutes after halftime ⁠either, resulting in a triple substitution that proved to be the difference.
