Dortmund go top after beating Real

Borussia Dortmund claimed a 2-1 win over Real Madrid in Germany to go top of Group D in the Champions League.

Robert Lewandowski netted a 36th-minute opener for the Germans and, although Cristiano Ronaldo cancelled it out within two minutes, Marcel Schmelzer hit the home side's winner in the 64th minute.

Manchester City lost 3-1 to Ajax in the group's other game to leave Dortmund top ahead of Jose Mourinho's men, while City sit bottom with just a point from their first three games.

Schalke's 2-0 win at the Emirates shattered Arsenal's 100 per cent start in Group B and threw qualification wide open as Greek side Olympiacos claimed their first points by coming from behind to beat Montpellier 2-1 in France.

Gaetan Charbonnier gave Montpellier a 49th-minute lead before Vassilas Torosidis struck a 73rd-minute equaliser and substitute Kostas Mitroglou poked home a dramatic injury-time winner on the counter-attack.

Those results sent Schalke to the top of Group B on seven points, one ahead of the Gunners, with Olympiacos moving up to three points and Montpellier bringing up the rear on one.

On a night of surprises, Malaga extended their lead at the top of Group C to three points as they beat AC Milan 1-0, Joaquin grabbing the only goal of the game in the 64th minute from a through-ball by Manuel Iturra.

Also in Group C, Zenit St Petersburg emerged as serious contenders with a 1-0 win over Anderlecht in Russia. Alexander Kerzhakov netted a 72nd-minute winner from the penalty spot after Milan Jovanovic fouled Alexander Anyukov in the box.

In Group A, Porto maintained their 100 per cent record with a 3-2 win over Dynamo Kiev in Portugal. The visitors twice struck back from behind with Oleg Gusev and Ideye Brown cancelling out strikes from Silvestre Varela and Jackson Martinez respectively, before Martinez's second won the game 12 minutes from time.

Also in Group A, Paris St Germain moved clear in second place with a 2-0 win over Dinamo Zagreb in Croatia. Zlatan Ibrahimovic opened the scoring on 32 minutes and Jeremy Menez made it two before half-time.
