Borussia Monchengladbach remain top of the Bundesliga after a last-minute penalty saw them defeat reigning champions Bayern Munich 2-1.

Ivan Perisic gave Bayern the lead shortly after half-time but were swiftly pegged back when Ramy Bensebaini struck after an hour.

Javi Martinez was sent off for conceding the stoppage-time penalty and Bensebain made no mistake from 12 yards.

Bayern had an early chance when Kingsley Coman crossed to Thomas Muller in the second minute, but the resulting strike fell straight into the hands of Gladbach keeper Yann Sommer.

Muller tried his luck again moments later, but again his effort fell short as the ball swung wide of the net.

Robert Lewandowski chipped inches wide of the post before returning for a second effort that again missed the target.

Muller was then thwarted for the third time when Sommer blocked a goal-bound shot and that near-miss was followed by another as Joshua Kimmich's shot was stopped millimetres short of the line and no goal was awarded.

Having dominated the first half, Bayern broke the deadlock after the break as Perisic cut inside and found Muller, who returned the ball to him before the Croatian winger volleyed into the top corner.

Gladbach were swift in their response, levelling when Jonas Hofmann's corner found Bensebaini, who delivered a powerful header.

The hosts were bolstered and began to dominate, producing a chance when Breel Embolo found Lars Stindl after Marcus Thuram broke through the Bayern defence.

Stindl's shot curled just wide of the post and Embolo was  unable to get a foot to it as it flashed across goal.

A raft of bookings followed as both teams became frustrated by the stalemate, and crucially Martinez collected two in eight minutes and was dismissed – the latter for a trip that handed the home side the decisive penalty.

Bensebaini stepped forward to convert the resulting spot-kick to seal victory for Gladbach.
