Bremen sweat on Almeida, welcome back Sanogo

Werder Bremen are sweating on the fitness of their Portuguese goal-scorer Hugo Almeida as they prepare to face Duisburg on Saturday.

The 23-year-old Portugal international has scored six goals already this season, five in the Bundesliga, but missed training on Friday after picking up a foot injury in his side's 3-1 Champions League defeat to Olympiakos in midweek.

"He took a heavy knock to the foot against Olympiakos, but we are hoping he will be fit to face Duisburg, we will have to wait and see," said Bremen coach Thomas Schaaf on Friday.

Almeida travelled with the squad to Duisburg, but Bremen have top-scorer Boubacar Sanogo - who has netted seven times this season with five of them in the Bundesliga - back from a hip injury.
