Former Bayern Munich midfielder Stefan Effenberg has attacked David Beckham's style of play, labelling the AC Milan loan star as ''underhand''.
One-time Germany international Effenberg claimed the ex-England skipper drew a comparison with the Roy Keane, arguing that Beckham was not as fair on the field as his former Manchester United team-mate.
Beckham and Effenberg locked horns numerous times in the Champions League, most notably the final in 1999, a game Keane missed through suspension, and which saw United come from behind netting two late goals to defeat Bayern.
Talking in Germany's Bild newspaper, Effenberg was asked about his duels with the former England captain.
''Yes, there were (duels),'' said Effenberg. ''Also with Roy Keane. But Beckham was the more underhand of the pair. Roy Keane was hard and fair. He came from in front, knocked you away, everything was wonderful.
''But Beckham always came from behind, in the Achilles, I didn't like that.
''You didn't see him, and suddenly he clobbered you from behind in the tendon. No, Beckham was underhand.''
