Bayern Munich legend Lothar Matthaus has warned Manchester City not to underestimate his old team.
Bayern host the second-leg of their Champions League quarterfinal needing to overturn City's 3-0 aggregate lead.
And Matthaus told Sky Deutschland: "Miracles sometimes happen, why don't they happen at the Allianz Arena? If the management, the players and the coach believe in a comeback after 0:3, then I believe in it.
"I often participated in comebacks as a player, including playing against Bayern. With Inter we won 2-0 in Munich, and then Bayern did well in Milan - we were eliminated from the tournament with a score of 1-3.
"Of course, everything must match for Thomas Tuchel's team: Sommer must catch every ball, and field players must score many goals even without the nine."
