BERLIN - Germany have called up marksman Sidney Sam to add more punch to their attack against Scotland on Sunday.

Sam's inclusion follows a string of absences and lack of firepower that contributed to a 4-2 defeat by Argentina in a friendly on Wednesday.

With the Fifa World Cup winners looking far from their polished best and missing several key players, head coach Joachim Loew wants more goal threat for his team's first Euro 2016 qualifier in Dortmund.

Schalke 04 forward Sam will increase Loew's options after Mario Gomez squandered three clear chances against Argentina and was jeered by his own fans.

"You could see that a large number of our players only had a short preparation this season," Loew said after the loss in Duesseldorf to their World Cup final opponents.

"We only had two days together as a team and on top of that we were missing a lot of players who cannot be replaced that easily."

Loew will also be without Mesut Özil and Mats Hummels against Scotland, joining new captain Bastian Schweinsteiger, among others, on the sidelines.

Julian Draxler has been ruled out with a muscle injury picked up against Argentina and defender Jerome Boateng is doubtful.

"I hope that at least Jerome can be at our disposal against Scotland. We need a bit of patience for the defence to find a good footing," the coach said after Argentine Angel di Maria charged down the wings, setting up three goals before scoring the fourth.

The 54-year-old mentor added: "On Sunday, it will be a completely different game from our side." - Reuters
