Bayern Munich winger Arjen Robben has said that his side's 3-0 win away at Borussia Dortmund was hard fought.

Robben scored the second goal of the evening and Thomas Muller wrapped up the win for Pep Guardiola's team after former Dortmund man Mario Gotze had put the away side ahead.

"It looks clear-cut but it was only 1-0 until the 85th minute," Robben told BBC Sport. "They had to force things at the end and we used the space."

The win leaves Bayern four points clear at the top of the Bundesliga table.
