Lukas Podolski is doubtful for Germany's EURO 2008 quarter-finals clash with Portugal after sustaining a calf injury in the 1-0 win Austria. "He definitely won't train today and it's going to be tight for Thursday," Germany coach Joachim Loew said. "The medical department will do everything they can to get him fit but he had real problems in the second half against Austria". The Bayern Munich man has been arguably Germany's best player so far in the competition, where he scored three goals out of his side's four.
