Today is midfielder Sami Khedira's 75th appearance for Germany - his first, back in 2009, was also in Leverkusen.

We're under way now in Leverkusen.

Where's this famous German efficiency? The game was meant to start three minutes ago.

A good environmental move from Germany...

In another friendly between Croatia and Senegal, the Balkan side have just equalised through Ivan Perisic. Ismaila Sarr had given Senegal the lead.

All of Saudi Arabia's players are based in their home country, although three did go on loan to Spanish clubs last season.

Fahad Al Muwallad, Yahya Al Shehri and Salem Al Dawsari were part of a group of nine Saudi players who went on loan - at no cost to the Spanish clubs - to La Liga and second division clubs.

However the trio made a combined 59 minutes of league appearances in four months - and the other six aren't in the squad.

Saudi Arabia have won two of their last seven games - all friendlies.

Juan Antonio Pizzi's side are in Group A with hosts Russia, Egypt and Uruguay.

Can you name the 22 players who started the 2014 World Cup final between Germany and Argentina?

Mesut Ozil misses out with a knee injury, but he's expected to be fit in time for the World Cup.

Manuel Neuer keeps his place in goal after making his return from nine months out the other day. Jerome Boateng plays for the first time since suffering an injury against Real Madrid in the Champions League semi-final first leg.

Mats Hummels, Toni Kroos, Timo Werner, Marco Reus, Thomas Muller and Julian Draxler also come in.

Saudi Arabia make six changes from their 3-0 defeat by Peru - including the return of experienced defenders Omar and Osama Hawsawi, who are not related.

Germany have played Saudi Arabia twice, winning both, scoring 11 goals and conceding none.

They met in the 2002 World Cup, with Miroslav Klose scoring a hat-trick of headers in an 8-0 win.

Their previous meeting was a 1998 friendly, with the Germans won 3-0.

Germany are the world champions, having beaten Argentina in the final four years ago.

But their decision to set up difficult friendlies might have backfired as they have not won in FIVE games now - their worst run since March 1988. They have lost two in a row.

Since qualifying they have drawn with England, France and Spain and lost to Brazil and Austria.

They are in Group F with Mexico, Sweden and South Korea.

Q. What do you do when you're on your worst run of results since 1988 going into the World Cup you're hoping to successfully defend?

A. Play a team who you beat 8-0 in your last meeting before flying to Russia.
