Michael Ballack has branded Chelsea underdogs in Saturday’s Champions League final but insisted they could “upset the odds” against Bayern Munich.

Former Germany captain Ballack spent four years with both clubs and was part of the Blues side beaten on penalties by Manchester United in their only previous final appearance in 2008.

The 35-year-old said: “Of course Chelsea can upset the odds — they did it against Barcelona (in the semi-finals),” Ballack told Chelsea TV.

“Everything looks like Bayern are favourites, they are playing at home which is a big advantage in a final. They kicked out Real Madrid in the semis. They have a good team and were in the final two years ago, when they lost against Inter Milan, so they’re very hungry.”
