Kompany had been out since the start of September with groin problems while Jarolim was recovering from a fractured arm.

Jarolim will be wearing a plaster for the group G fixture, Hamburg's first in the competition since the 2000-01 season.

Hamburg coach Thomas Doll will however have to do without skipper and playmaker Rafael van der Vaart, who is still nursing a left thigh injury.

Other injured players missing from his squad are Timothee Atouba and Argentine Juan Pablo Sorin.

Despite failing to win any of their three Premiership matches so far, Arsenal go into this fixture as big favourites. Arsene Wenger's men lost to Barcelona in last year's final in Paris.

With three league draws and an early exit from the German Cup on Saturday, Hamburg have had a less than spectacular start to the domestic season.

Doll however remains upbeat.

"It will be a match that could help turn things around for us," said the German.

"It will give us a chance to stop thinking about the Bundesliga and the German Cup for a while."
