Berlin: Wolfsburg's ex-Bayern Munich midfielder Hasan Salihamidzic was furious after his side were denied a first-half goal in their 1-0 defeat to the Bavarian giants on Saturday.
Bosnia's Salihamidzic, 34, spent nine years at Bayern and won the 2001 Champions League title with the Munich side, but has signed for Wolfsbgurg after a four-year spell in Italy with Juventus.
Having been shocked at home to Borussia Moenchengladbach last Sunday, Bayern picked up their first win as Brazil midfielder Luiz Gustavo scored in the 91st minute at 2009 champions Wolfsburg.
But Wolves were denied a first-half goal from Patrick Helmes after the referee ruled the header offside, but later admitted he made a mistake.
"We’re obviously gutted and I’m incredibly angry," said Salihamidzic.
"We played well and we scored a perfectly good goal, but at the end of the day, Bayern are in the changing room not quite knowing how they’ve won.
"I thought we controlled it well in the first half. We might have let the ball do more of the work, and that would have given us more space, although that’s never going to be easy against Bayern. I think a draw would have been the right result."
Bayern's French play-maker Franck Ribery, who provided Gustavo with the final pass, admitted his side enjoyed some luck.
"We were a bit lucky in the last couple of minutes, but I do think we saw a different Bayern compared to last week," said Ribery.
"We were more aggressive and we went for it. It's never going to be easy against a good team like Wolfsburg. The three points were crucial, and important to us mentally.
"We need to play like we did against Wolfsburg every Saturday."
But Wolfsburg coach Felix Magath called for video referees to be introduced in Germany after the refereeing blunder cost his side a point.
"If four referees are not able to assess a scene properly, then it's time for the television evidence," fumed Magath.
Defending champions Dortmund suffered a 1-0 defeat at Hoffenheim as they never recovered after suffering an early goal.
Hoffenheim's Sejad Salihovic curled in a free-kick from 30 metres out after just nine minutes leaving even Dortmund coach Jurgen Klopp impressed.
"That was one of the goals of the season from Salihovic," said Klopp.
"I do not know about any other goals scored in the league today, but that must have been hard to top. Hoffenheim got the victory because they showed greater passion.
"In spite of that, we could have still managed to win the game.
"Over 40 to 50 minutes, we played well and created a number of chances to score"
