Undav's double in the dramatic 2-1 comeback win over Ivory Coast again underlined his value, sending Die Mannschaft into the knockout stages of the World Cup for the first time since their victorious 2014 campaign. With three goals and two assists, the striker has five goal involvements in two appearances off the bench - the joint-most by a substitute at a World Cup since 1966 (tying Cameroon's Roger Milla in 1990). But the 29-year-old's place in Germany's World Cup squad was far from certain after a public row with Nagelsmann following his last-gasp winner as a substitute against Ghana in March. Undav had spoken openly of his ambition to push for a starting role with Germany - only for the former RB Leipzig and Bayern Munich manager to respond by warning he was placing unnecessary pressure on himself with such comments. Nagelsmann suggested Undav would not have scored had he played from the start, before later revealing he had apologised to the forward. And Undav has since let his football do the talking - in emphatic fashion. So much so that he is now in serious contention for a starting spot at the World Cup, after taking his tally to nine goals in 11 international matches. "Yes, definitely," Nagelsmann said after Saturday's win, when asked whether Undav could start Germany's final group game against Ecuador on Thursday (21:00 BST).

It is only the latest chapter in a remarkable journey for a striker who has made a career of defying expectations. 'I had to do that job for the money to live' With his double against the Ivorians, Undav became the first German to score in his first two World Cup appearances since Miroslav Klose in 2002. That is elite company - but at one stage even taking part in a World Cup was a distant dream for Undav, who was rejected by Werder Bremen aged 14. At 17, he was earning £120 a week as a semi-professional in the German fourth tier while balancing his footballing career with eight-hour shifts at a factory. "When Werder told me at 14 that I didn't have a future with them because I was too small, it broke my heart," Undav said in an interview with Belgian outlet 7sur7. "But I did not abandon hope. I left the family home at 17 to sign for Havelse in the fourth division in Germany where I combined playing and training with working full-time, eight-hour days operating a laser machine in a factory. "I got up around 4am, went to the factory, then I went to training and got back home around 8pm... before doing it all again the
