Stefan Effenberg defends Robert Lewandowski form

Former Bayern Munich midfielder Stefan Effenberg has hit out at critics of Robert Lewandowski's form since his arrival at the Allianz Arena.

The Polish forward returned to his best with a brace in Saturday's 6-0 thrashing of SC Paderborn, and Effenberg believes that the 26-year-old, who moved to the club on a free transfer after leaving Borussia Dortmund last summer, is doing a good job of sharing the spotlight with Bayern's world-class attacking talent.

"People who say that Lewandowski was a dodgy purchase have no idea what they're talking about when it comes to football," Effenberg told Sky. "He is extremely important to the team.

"The charisma and quality that he had at Dortmund, he has at Bayern. The difference is that at the Allianz Arena he has three or four other world-class attackers alongside him."

Lewandowski has scored 13 goals in all competitions this season.
