Former Bayern Munich star Michael Ballack is worried about facing Manchester City tonight.

Bayern are at City tonight in the first-leg of the Champions League quarterfinal.

Ballack said, "I'm a fan of Pep (Guardiola), he has everything a great coach needs.

"Bayern is Bayern, a team feared across Europe, across the world, nobody wants to play against them in any competition.

"They have this brutal quality, a lot of experience and it has internalized what it takes to win.

"City took (Erling) Haaland who was what they lacked to play in another way and have a plan B from tiki-taka."
