HALF TIME: BORUSSIA DORTMUND 0 - 1 BAYERN MUNICH

Weigl booked for a late challenge on Goretzka.
That goal wont dent the atmosphere here, however Bayern deservedly take the lead.

GOOD FROM NEUER: He's at it again, Manuel Neuer stops what would have been a definite goal, he intercepted a squared cross, with Jadon Sancho waiting to tap the ball home.
PENALTY!? More drama, Robert Lewandowski wants a penalty and appeals to the referee, however nothing is awarded. Replays show that it was the correct decision.
