Galatasaray boosted their hopes of reaching the knockout stage of the Champions League with victory at home to Stuttgart.

The Turkish champions struck twice in the space of three first-half minutes to take control of the contest and condemn their German opponents to a first defeat of the league phase.

Aleksey Batrakov opened the scoring in the 12th minute when he fired home an effort after a Roland Sallai cross was cleared to him on the edge of the area.

The Russian soon made it two when he was expertly played through by a low pass from deep by former Tottenham defender Davinson Sanchez, before slotting the ball through the legs of visiting keeper Fabian Bredlow.

It was a difficult start for Stuttgart, who had arrived in Istanbul unbeaten in Europe this season after taking seven points from their opening three matches.

Jamie Leweling nearly opened the scoring for the German side, but his low finish struck the far post, rebounded on to the near post and bounced to safety.

They struggled to deal with the relentless Galatasaray pressure and relieved the hosts were wasteful in the final third or they would have extended their lead.

Stuttgart thought they had pulled one back when Chris Fuhrich bent an effort into the far corner from the edge of the area, but his goal was chalked off for an offside in the build-up against Deniz Undav, who had hit the bar.

The result gave Galatasaray back-to-back Champions League victories following their 4-2 win at Lille, moving them to six points after four matches, while Stuttgart remained on seven.
