Bayern Munich head coach Carlo Ancelotti has defended the rise of RB Leipzig ahead of a top-of-the-table Bundesliga clash between the sides on Wednesday.

Leipzig's remarkable ascent to the top of German football and the influence of their wealthy backers have proved controversial this season, with the newly promoted side sitting second after 15 matches.

But Ancelotti is prepared to look beyond the money and focus on Leipzig's on-field qualities.

"This is the perfect game for anyone who loves football," he said ahead of the match between the two sides separated by goal difference at the Bundesliga's summit.

"Tomorrow we will see two sides who play with very different styles. We will stay true to our style and assert ourselves. We will stand strong defensively and find the right balance.

"We need to put on a strong performance. We are playing against second in the Bundesliga.

"Leipzig are a good, young team that plays football with a lot of enthusiasm.

"Money isn't the most important thing in football. The balance is right at Leipzig and their success gives them confidence.

"The key to victory is having the right balance between attack and defence. Leipzig are dangerous on the break so we need to be wary of that."

Ancelotti confirmed both Arjen Robben and Philipp Lahm are fit following recent injuries, while Jerome Boateng has been ruled out for six weeks after surgery on a pectoral tendon.
