FRANKFURT, May 5 (Bundesliga) - Eintracht Frankfurt went some way to easing their relegation fears and plunged 10-man Alemannia Aachen deeper into the mire with a comprehensive victory at the Commerzbank-Arena.

The hosts dominated the match from start to finish in front of a sell-out crowd of 55,000, as goals from Benjamin Huggel, Aleksander Vasoski, Naohiro Takahara and Benjamin Kohler saw off a lacklustre challenge from Aachen, who had Alexander Klitzpera sent-off in the second half for a reckless challenge.

Frankfurt got off to a dream start when in the third minute Matthias Heidrich's attempted clearance fell to Huggel, who turned impressively to power the ball into the bottom left-hand corner.

The hosts were in confident mood and refused to rest on their early advantage.

They came close to doubling their lead at the mid-way point when Takahara was sent through by Michael Fink but spurned his opportunity.

But Frankfurt did not have to wait much longer for their second goal to arrive, and it came in the 30th minute through Vasoski.

The big defender rose at the back post to power home a header past Aachen goalkeeper Kristian Nicht and send the hosts into the break with a deserved two-goal lead.

The visitors changed things around at the interval, bringing on Marius Ebbers and Moses Sichone in an attempt to provide more of an attacking threat.

But their plans were dashed just 10 minutes into the second period when Klitzpera received his marching orders for making a desperate lunge on Kohler, who was clean through on goal.

And things got worse for Aachen when they failed to properly clear Albert Streit's resulting free-kick and Takahara was on hand to tap home.

Things were wrapped up in the 80th minute when Kohler netted his first goal of the season.

Christoph Spycher finished off his searching run with a shot which was only parried by Nicht, leaving Kohler with the easiest of finishes.
