Bayern Munich winger Arjen Robben has called new teammate Douglas Costa their "special weapon" after he helped the champions thrash Hamburg in the Bundesliga opener.

The Brazilian winger, a new signing from Shakhtar Donetsk, started on the opposite flank to his Dutch counterpart as Die Roten beat Hamburg 5-0 at Allianz Arena on Friday.

"He's a talent," Robben told Bayern's official website.  "He can sidestep his opponents and is a special weapon for us."

The 24-year-old got a goal in the closing stages of his debut after Mehdi Benatia, Robert Lewandowski, and a Thomas Muller brace had already wrapped up the points, and also provided the assist for Muller's first.

"I really liked it," Costa said of the match. "It was a successful start and I'm very happy that I played my part in the victory."
