Borussia Dortmund moved seven points clear at the top of the Bundesliga after Paco Alcacer hit the winner against rivals Bayern Munich.

Paco Alcacer came off the bench to score a wonderful winner as Borussia Dortmund completed a stunning comeback to down Bundesliga rivals Bayern Munich 3-2 in a brilliant Klassiker.

Marco Reus twice cancelled out Robert Lewandowski goals, but it was Alcacer who struck the decisive blow in the 73rd minute at Signal Iduna Park on Saturday.

Dortmund had a four-point cushion to the Bundesliga champions heading into the clash and their seven-point gap will now give them real hope of a title challenge, although they were spared a last-gasp Lewandowski leveller by a correct offside call.
