Borussia Dortmund have booked their place in the Champions League knockout stages with a 4-1 win against Galatasaray in Group D.

The Germans controlled the opening stages, but it was the visitors who carved out the first clear-cut chance when Wesley Sneijder met Blerim Dzemaili's cross with an overhead kick, failing to muster enough power to trouble Roman Weidenfeller.

Reus had a lively first half, and Dortmund almost took the lead from one of his crosses in the 24th minute, Sokratis Papastathopoulos leaping high and heading against the bar from close range.

It was Reus who was on target when Dortmund edged their noses in front five minutes before the break. Lukasz Piszczek cut the Galatasaray defence in half with a through-ball, and the winger raced clear to slide the ball home.

Things could have been worse for the Turks at half time, but Henrikh Mkhitaryan's strike following a neat Dortmund team move sailed narrowly over the crossbar.

Papastathopoulos was unlucky not to get his name on the scoresheet in the first half, but he went one better 10 minutes into the second, collecting Sven Bender's nod-on inside the area and drilling home.

It was game on in the 70th minute when a Sneijder corner was headed home by Hakan Balta to hand Galatasaray a lifeline, but four minutes later, their hopes were dashed.

Dortmund restored the two goal cushion through substitute Ciro Immobile, who scrambled the ball home after being picked out by Pierre-Emerick Aubameyang following a swift break.

Things got even worse for the Turkish side before the full-time whistle as Semih Kaya deflected an Immobile volley into his own net to add insult to injury.

The match was marred by crowd trouble as the visiting supporters hurled flares onto the pitch during the second period, and then into the home stand ahead of the final whistle, actions that will likely see Galatasaray face sanctions in the wake of the game.
