The Bundesliga side took the lead in the 11th minute when Deniz Undav selflessly squared the ball for Leweling to finish past Dominik Takac.

The visitors pulled further clear soon after when a long punt forward was gathered by Enzo Millot who saw his effort saved by Takac, but Leweling was on hand to tuck away the rebound, with the goal eventually given after a video assistant referee review for offside.

Despite squandering glorious chances to extend its lead through Maximilian Mittelstadt and Undav, Stuttgart was pegged back with five minutes remaining.

Bratislava substitutes Tigran Barseghyan and Idjessi Metsoko combined brilliantly to reduce the deficit, with the latter squeezing a left-footed effort past Alexander Nubel.

But less than two minutes later, Stuttgart sealed the win when Mittelstadt picked out Fabian Rieder, who took his time before tucking the ball into the net.

With defeat, second-bottom Bratislava became the first side in UEFA Champions League history to lose its first seven matches in the competition.
