Bayern Munich boss Niko Kovac plays down talk of domestic double

"We need to focus on the first game, we have to win that first," Kovac told fcbayern.com.

"We're up against an opponent in really good form. They're still unbeaten this year and have scored in every game."

Bremen are the only Bundesliga club to have found the net in all of their 29 matches so far this season and currently sit in seventh place, one point shy of the Europa League qualifying places.

Kovac added: "Things are going well of late. We've played really well, scored a lot of goals and conceded very few. The team feels assured now."

The 47-year-old Croatian will have a number of selection dilemmas for the double-header.

Niklas Sule is suspended in the cup and the manager does not want to take any chances with Mats Hummels, while James Rodriguez also remains a doubt for Saturday's game.

Bayern will also be without Arjen Robben, who is undergoing rehabilitation training, and goalkeeper Manuel Neuer, who sustained a muscle fibre tear in his calf during the 4-1 win at Fortuna Dusseldorf on Sunday.

Neuer is just as cautious as his manager, adding: "We're just playing finals now.

"We have to invest everything to come out on top in the end."

Florian Kohfeldt insisted his Bremen side were aware of the challenge they will face at the Allianz Arena on Saturday.

"The team know what lies ahead of them," Kohfeldt told werder.de.

"We're up against an opponent who have proven they are the strongest team in Germany.

"There is no plan in existence that could take all of their strengths out of the game."

He added: "We're also capable of turning a game in our favour. It's clear that we need to put forth a strong performance and for Bayern to not have such a great day.
