Chelsea midfielder Michael Ballack has warned Manchester United they can easily let the Premiership title slip on Sunday.
And, as he looked ahead to what could be one of the best days of his life, the Germany captain recalled one of the worst in 2002.
He said: "With (Bayer) Leverkusen, I was in the position that United are in now.
"It's different for Chelsea this season because we were always the team chasing. But I know what it's like to be on the other side of this situation.
"In the last game we needed just a draw and Bayern Munich needed to win.
"We lost and it was even against a lower team in the league - Unterhaching - so believe me, I know that anything is possible and it's possible it could happen next weekend."
