FRANKFURT, Germany (AP) — Defending champion Bayern Munich puts its six-match winning streak on the line against Viktoria Plzen in Group D of the Champions League on Tuesday.

Also, Manchester City hosts CSKA Moscow, the team it beat 2-1 on the road despite racist chants against Yaya Toure.

Here are 5 things to know ahead of Tuesday's matches:

___

SUPPORT THE PRESDIENT

Bayern's board is standing behind club president Uli Hoeness ahead of his trial on tax-evasion charges.

The board says it sees no reason for Hoeness to step down although he is scheduled to go on trial in March over an undeclared private Swiss bank account.

Hoeness, a former Bayern and Germany star, is the most successful manager in German football and engineered Bayern's rise to one of the top clubs in the world.

The affair broke out in April and did not prevent Bayern from sweeping the Bundesliga title, the German Cup and the Champions League in an unprecedented triple for a German club.

____

ROBBEN OUT

Pep Guardiola's team left Munich without Netherlands winger Arjen Robben, who is nursing a groin injury.

Guardiola was not pleased with his team's workmanlike 2-1 Bundesliga victory in Hoffenheim, saying he needs to make "corrections," without giving details.

Bayern won 5-0 at home against Viktoria and it could secure a place in the second round if it wins and Manchester City does not lose against CSKA.

If it wins its seventh consecutive match in the Champions League (over two seasons), Bayern will equal Barcelona's record from the 2002-03 season. Bayern has won 12 of its last 14 Champions League games.

"We are leaders ... and we want to qualify early, so that we can move our focus a little bit more toward the Bundelsiga," club chairman Karl-Heinz Rummenigge said. "You have to show respect for the opponent and not come in with arrogance. I hope the team will play as well as in the previous three Champions League matches."

LESSON LEARNED?

Viktoria seems to be in a better frame of mind after coming off a 6-1 thrashing of Jablonec in the Czech league, although Bayern is another class.

"We saw the video from the previous game against Bayern and there was hardly anything positive for us," Viktoria defender Marian Cisovsky said. "We want to play much better in front of our fans."

____

ON THE ROAD

CSKA travels to Manchester for its first European match since the Russian champions were punished by UEFA for "racist behavior" by their fans.

CSKA was given a partial stadium ban for its next home Champions League game against Bayern on Nov. 27.

At home, CSKA has won three straight and midfielder Zoran Tosic also is on a hot scoring streak. Tosic has four goals in the last two Russian league games and has scored in the last two Champions League matches as well.

If it wins at City, CSKA will pull even with the Manchester team, both with six points.

____

ON BENCH?

Joe Hart is likely to remain on the bench for City after replacement Costel Pantilimon kept a clean sheet in a 7-0 rout of Norwich.

The England goalkeeper lost his place in the City side as manager Manuel Pellegrini decided his costly mistake in the previous week's loss at Chelsea was one error too many.

Midfielder Fernandinho believes what has happened to Hart is a strong reminder of the high standards demanded at City.

"If the quality is a bit off you must work harder to recover your position and your best quality," Fernandinho said. "If he (Hart) at the moment is not (at his best), he must work more hard. But they are very good keepers, he and Pantilimon."
