Bayern Munich coach Jupp Heynckes said his side took a significant step toward the Bundesliga title after its 3-0 win at Mainz 05 opened up a 14-point lead at the top of the table.

Croatia striker Mario Mandzukic scored twice as Bayern made its superior possession count at fifth-placed Mainz on Saturday.

"We prepared extremely thoroughly, that was a very important victory on the road to the title," said Heynckes, after his side picked up its 16th win from 20 league matches.
