Michael Ballack has warned critics not to write off Chelsea's Premiership title tilt.
Their 3-1 defeat at Wigan last month, not to mention FIFA's transfer ban, led to more predictions of doom and gloom but Ballack says Chelsea can never be written off.
He told the official Chelsea magazine: "Sometimes people underestimate players or clubs. You shouldn't do this, especially with teams like Germany or Chelsea, where there is so much strength and experience.
"We believe in ourselves and that's the important thing. Even if you have a bad day, you always have to believe in your own strength. If you work hard, then success will come back.
"Most of the players are together for a long time and you can feel this, there's a good mentality in the group. Everybody is part of this team and making it successful."
