Former Bayern Munich striker Claudio Pizarro came off the bench to score an equaliser that left Borussia Dortmund's Bundesliga title hopes hanging by a thread after they threw away a two-goal lead in the last 20 minutes to draw 2-2 at Werder Bremen.

Lucien Favre's men looked to have recovered from a disastrous 4-2 Revierderby defeat at home to Schalke last time out as goals from Christian Pulisic and Paco Alcacer put them 2-0 up at half time.

But two calamitous moments involving goalkeeper Roman Burki and defender Manuel Akanji undid Dortmund's hard work and allowed Kevin Mohwald and Pizarro to drag Werder level.

The result, along with Bayern's 3-1 victory over Hannover earlier in the day, left second-placed Dortmund four points behind the champions with two games left to play, and even winning them both may well not be enough.
