Die Mannschaft were stunned by a 2-1 defeat to Japan in their opener, with Ilkay Gundogan’s goal wiped out by two strikes in the final 15 minutes from Japan.

The defeat extended a miserable recent finals record for Germany, who were knocked out of the 2018 World Cup at the group stage and have won just two of their last eight tournament matches. Meanwhile, Spain thumped Costa Rica 7-0 last Wednesday and could condemn Germany to another early exit with victory at the Al Bayt Stadium.

Havertz admitted that the players and staff have been poring over the video of their surprising loss and he knows finding solutions quickly will be key if Hansi Flick’s men are to get their World Cup campaign back on track.

‘We’ve analysed the game well over the last few days,’ said Havertz at a press conference in Doha. ‘We saw what went wrong and what we need to do better so now it’s just a matter of us approaching this next match together and giving it our all.

‘It will be a tough game but we will be prepared. 7-0 is a strong result so we obviously have to respect Spain. We know they are of high quality but we don’t hide because we know what we can do.’

Havertz started up front against the Japanese and was irritated when question marks about his best role in the team resurfaced at the press conference.

He has faced similar speculation about the most effective position for him in the Chelsea team but insisted his versatility should not count against him, even if he acknowledges the need to find the back of the net when playing as a centre-forward. The closest he came against Japan was an effort ruled out for a narrow offside.

‘The position issue is getting on my nerves now,’ he said. ‘Everyone knows that I can play on the right, on the left, as a number nine and as a number 10. Of course the positions are different but I can play anywhere up front.

‘I like the striker position but I also know that as a striker, you have an obligation to score goals. If I play there on Sunday, I’ll give my best once more.’

A difficult UEFA Nations League campaign and round-of-16 exit to England at the European Championship last summer have increased the pressure on Germany but Havertz is backing his own experience of backs-against-the-wall football to help the team through.

‘In the past few years there has been an overhaul of the team, a change of coach and new players so that does play a role but it’s not an excuse,’ he added.

‘At the end of the day, what matters are the tournaments so we have to turn things around. We are all in the same boat and we know what is at stake.

‘We are in a bad moment now but that can switch around quite fast. It can be the turning point for us. It is a big game but I’m lucky because I’ve played a few big games at Chelsea.’
