Germany boss Flick puts pressure on veteran Hummels

Hummels has had "an excellent, very successful past in the national team", Flick told broadcaster RTL, "but at the moment -- he knows himself -- he doesn't have that level, that quality in his game."

Flick says Hummels has "one or two problems" to fix with the centre-back at the heart of a Dortmund defence which has struggled for consistency this season.

As a key member of the team which won the 2014 World Cup, the 32-year-old Hummels last played for Germany in a 2-0 defeat to England in the last 16 of Euro 2020 in June.

Hummels has made 76 international appearances and Flick has left the door open should the Dortmund defender prove his form.

"We are keeping the door open for all those who perform and have enormous quality," said Flick.

Flick replaced Joachim Loew as head coach of Germany in September and Hummels has yet to play under the new national team boss.

In his absence, Germany punched their ticket for next year's World Cup, which kicks off on November 21 with the final on December 18, 2022.

The defender is carrying a persistent knee problem and Flick has so far said he resisted calling up Hummels to allow him more time to rest.

Hummels, Thomas Mueller and Jerome Boateng were all axed from the national squad by Loew in March 2019 due to the team's disastrous World Cup campaign in 2018.

Following a change of heart by Loew, Mueller and Hummels were recalled for the Euro 2020 finals.
