Wolfsburg, M'gladbach settle for draw
Borussia Monchengladbach's surge up the Bundesliga table was slowed by Wolfsburg, who became the first side in 2012 to take a point off Lucien Favre's side with a 0-0 draw at the VW-Arena.
Both sides had goals disallowed for offside while Marco Reus missed a glorious opportunity to give Gladbach their fourth straight win in the second half.
But a draw was a fair result as the visitors at least moved level on points with Bayern Munich while Wolfsburg remain in mid-table.
Gladbach made a bright start, buoyed by their three wins in a row, but they were unable to transform their dominance of possession into chances.
The first chance of the game came at the other end in the 28th minute when Petr Jiracek pulled the ball back to Sebastian Polter, but his very weak shot was easy for Marc-Andre ter Stegen in the Gladbach goal.
Gladbach had the ball in the back of the net in the 36th minute, but Mike Hanke's strike was ruled out for a very tight offside decision.
Wolfsburg's first big chance of the game came in the 53rd minute when Filipe Lopes headed a corner over the crossbar from six yards out.
A minute later, Josue saw his shot saved well by Ter Stegen as the Wolves started to raise the tempo of the game.
They too had a goal controversially ruled out for offside with Polter in an offside position before Giovanni Sio slid in to score at the far post.
Reus then missed the best chance of the game when he was put through on goal, but he tried to pass the ball to Hanke rather than shoot and appeared to be caught in two minds, resulting in neither a shot nor a pass as the ball went wide.
Filip Daems cut out Marcel Schafer's low cross towards Sio in the 77th minute as the home side finished the game on the front foot but failed to make a breakthrough.
