Werner has supplanted Mario Gomez as the Germans' first-choice striker and Kimmich, who has known the RB Leipzig man since he was 13, believes he has the ability to justify the faith shown in him by coach Joachim Low.

"I think he showed at the Confederations Cup last year and in the matches after that how good he is," Kimmich said. "With his speed he is a weapon for us. I've known him since I was 13 when we played together in the youth teams at Stuttgart.

"For me he's a very important player for us and I told him that I haven't been part of a tournament where he wasn't the leading goalscorer.

"At the moment, he's very calm but let's see how he is ahead of the first match."

Werner scored the last time the teams met, in the semi-finals of last year's Confederations Cup, a game Germany won 4-1.

Kimmich warned little should be read into that result, though, and admitted Mexico was the better side despite the one-sided scoreline.

"Our team has changed a lot compared to last year," he said. "Mexico has a lot of the same players still in their team.

"We had a good start in our last match [Germany led 2-0 inside eight minutes] but then they were better and we had to focus on defence.

"We had some luck with their mistakes but they were better and had more of the ball than us."

Mexico has been keeping a relatively low profile since arriving in Russia, something that cannot be said of its boisterous supporters who have been a visible presence on the streets of Moscow since the middle of the week.

Coach Juan Carlos Osorio's main headache leading into the Germany game is how to improve an impotent attack that has managed just one goal in the last four matches – Giovani dos Santos' effort against Scotland.

The country's all-time record goalscorer Javier Hernandez endured a disappointing season at West Ham and arrived in Russia without a goal in two months.

With Raul Jimenez and Oribe Peralta also failing to impress in the warm-up matches, Osorio may look to pack the midfield and try to play on the break against Low's men.
