Just four minutes later and the hosts had got their second goal, Reinartz heading home Barnetta's corner.

With just 11 minutes on the clock Leverkusen had all but secured the points thanks to a third goal.

Alexander Meier sent in a soft shot as Frankfurt attempted to get a foothold in the game but the goalkeeper was easily able to save.

Marco Russ blocked Kiessling's pass from the right but Kroos pounced on the rebound to send a right-footed shot into the net from just outside the area.

Sami Hyppia had a header cleared off the line before the former Liverpool defender shot over the bar.

Eren Derdiyok and Gonzalo Castro both had shots for the league leaders in the second half before Bender got his side's fourth after 86 minutes.

Castro left the ball to Bender who ran with the ball before unleashing a shot from just outside the area as Leverkusen completed a straightforward victory.
