DFB president Gerhard Mayer-Vorfelder would like to see Germany coach Jurgen Klinsmann stay in his post beyond the World Cup finals this summer.

Klinsmann had faced a barrage of criticism before the tournament on home soil, but Germany's passage to the quarter-finals has convinced German FA chief Mayer-Vorfelder that progress is being made.

He told Sport1: "He realises that his work is paying off.

"It won't be easy to convince him, but the team could make his decision very easy if they beat Argentina.

"His steadfastness has been impressive. He always said the team needs to make the semi-finals at least.

"He is very ambitious and only satisfied if he can meet those goals.

"My own confidence has gone up after the win over Sweden. Our defence looks stable, the midfield is creative and our attacking department is always dangerous.

"The duel against Argentina will probably be one of the toughest and closest matches of the whole tournament. If we prevail everything will be possible."
